RABBIT MATING: If you have never bred your rabbit, you are in for a treat because watching a rabbit mate is probably one the funniest gifts nature has given us. It happens really fast and starts out the same as other species, but when a male rabbit completes his task, he locks up with his whole body (pulls his front and back legs in and curls into a ball) and freezes for several seconds, and because of this he will either roll backwards off the female or fall sideways. Strange and hilarious sounds may or may not accompany this, but thee fact that the male literally falls off of the female is why you will hear this referred to sometimes as just "falls," but I personally tend to refer to it as a "tie."
You can breed your rabbits in a few different ways. In my experience they tend to enjoy playing in the yard in a playpen and taking their time to court in the summer. This is enjoyable to watch them play and frolic and there doesn't usually need to be any human intervention. You can also breed your rabbits in the buck's cage (NEVER the does cage), and just remove the doe after they are done. Does are more territorial in this situation and while a male's hormones will take over and he will want to mate, a doe will not typically feel the same way when a buck invades her territory and bucks have been injured or died from being placed in doe cages for breeding. You can also table breed, which is the most hands-on method as you will need to be present at all times and be ready to catch your buck so he does not get injured when he ties and falls off.
Don't forget to do health checks on your buck and doe prior to breeding. See above for details.
CONCEPTION: My favorite part about breeding rabbits, is that you can work it around your own schedule. A dog, for example, will go into heat every 6-12 months and you need to breed her at the right time during her heat cycle to have a chance at puppies. Rabbits, on the other hand, are induced ovulators. This means that the act of mating, actually causes the rabbit to release the eggs to be fertilized on demand, which allows the magic of baby-making whenever it makes sense for you to do it.
PREGNANCY: Pregnancy lasts about 30 days in rabbits. If your rabbit has gone more than 33 days after mating without kits, it probably was not pregnant, or at some point reabsorbed the kits. In rare cases, I have heard of does delivering at 35 days, but I have not heard of live babies at that time.
Palpation (feeling the belly to see if your doe is pregnant) is best at 10-14 days to feel the tiny little marbles (baby butts and heads) in your rabbit's belly. I highly recommend you have a more experience breeder teach you how to do this properly before trying it yourself.
AGE TO BREED: Most breeders I know stick to the general rule of not breeding a rabbit for the first time before 6 months of age or after 12 months of age (some say 18 months, but we will come back to pros and cons on that). For your females to have larger and healthier litters, you do not want to breed before 6 months. They can typically get pregnant before 4 months of age, but in allowing them to do so, you actually can be jeopardizing their entire breeding career. You can stunt their growth and cause smaller future litters, and since they have not developed hormonally at this time they may not care for their kits, either never making a nest and allowing the babies to freeze to death, or not feeding them. Some does never really come back from that to be good moms. If you allow your doe to grow to their adult size at 6 months, it is safer and better long-term for the mom and babies. The reason most breeders will not breed a doe for the first time over a year is because around this time, their pelvis will fuse (the hyaline cartilage of the pelvis will have fully ossified). This just means that their pelvis may not be able to shift properly to allow the babies to pass through and you have a significantly higher likelihood of stuck kits for all future pregnancies, and if you do not already know, a stuck kit does not only kill the stuck baby, but the babies behind it waiting to come out, and in some cases can be fatal to mom if not caught in time.
Bucks can be bred very early, I have heard of bucks impregnating does by the age of 12 weeks old, but it is not ideal to breed your bucks at this age. Their sperm count has not reached it's peak and you will get larger litters from a buck who is 6 months or older. I have heard of younger bucks ending up with injuries, but that seems to be rare, typically what you get is an enthusiastic breeder who has no idea what he is doing and can't figure it out anyways. I just prefer to wait for the sperm count and motility to hit peak before I breed my boys, and that is right about 6 months.
KINDLING: If you have not heard the term yet, kindling is just the rabbit term for giving birth. Sometime in the days leading up to delivery, your doe should start making a nest of her fur (she literally plucks herself) and hay or whatever else she can find that she feels like using. In some cases, a doe may make the nest after giving birth, but in my experience it is usually first time moms. I love to watch my rabbits make nests because even though you cannot even imagine how they have gotten so much fur and/or hay in their mouth in the first place, they always find a way to fit more before they take it to the pile. If your does has good instincts and/or knows what she is doing, she will have her babies in the nest, clean them, eat the placenta, possibly feed them at this time and then wander off and ignore them for the next 12-24 hours. This typically happens early in the morning right before sunrise, but can happen any time if your doe is a rebel. Your main job as the breeder is to make sure those kits are in the nest and warm. If they don't have full bellies yet, this is totally ok, don't pressure mom into feeding them or she may destroy her nest and you will lose the babies to exposure anyways.
DAY 1: This is the day after they were born. At some point when you were not looking, your doe should have fed the babies, so their bellies should be a bit more round than the day before. Check the nest and the babies. Count the babies and make sure the number is the same as day 0 (day of birth). If you are missing a baby, find it. if it is dead, dispose of it, if it is cold, warm it. Using your body heat is the best way to ensure a safe temperature for the baby to warm up to. The other thing you want to be checking for (and this is rare to find) is urine from mom in the nest. If there is wet nest, you have to remove it for the health and safety of the babies. If there is not enough nesting material at any point for these naked little pink things to stay warm, you will have to shelf the kits.
SHELVING KITS: If for any reason you cannot trust your mom to leave the babies in a warm, fluffy nest, you need to remove the babies from mom's cage. The good news is, rabbits only feed their babies every 12-24 hours, so this is very easily done and allows for the babies to stay warm in cases where mom did not build a nest, likes to randomly destroy her nest, or urinates in it. Take a bit of time to gently groom momma rabbit to get what fur you can from her to build up the nest in the nest box (if you need to you can use hair from your other rabbits as well, and they also sell nest fluff for these occasions), and then remove the nest box from mom's cage. Make sure the babies are warm before you put them in the nest. They really can't generate much body heat before they have fur. Find somewhere safe to leave your nest box. I put it on a shelf in my bedroom, and importantly, my cats are not allowed in my bedroom when I am not in there or when I am sleeping. Really think about where you are putting this nest box and if you have to put it inside a cage to keep it safe from your other furry friends who happen to be predators, do it. Then all you have to do is bring mom in twice a day to feed the babies. I trust some of my moms just to hop in the nest box and do their thing, but other moms will just dig and be destructive. In this case, I fold up a towel and place it on my lap and put the babies down and then mom on top of them and pet mom and calm her, and feed her snacks (carrots usually do the trick, but if that doesn't work, a doe who just had babies really loves calf manna (you just have to give a very limited amount). Your goal is to get as close to 15 minutes as you can in keeping mom calm. These are prey animals and they have adapted to be anxious when they feed so they can lead predators away from their nest in case of an emergency, but the babies also fill up faster than other species like dogs and cats. Just make sure their bellies are more round than when they started. Also, after mom's part is done, make sure to take a baby wipe (unscented, unmedicated) and wipe the peri/anal area gently for a moment to stimulate urination and/or defecation. The first few days the urine will just dribble, but after a while they get a stream, so be mindful of where it is aiming. Then the kits go back to their nest and you are done. Usually by the time they are moving freely in and out of the nest box, they can go back with mom and stay warm be ok (unless mom is aggressive toward the babies).
DAY 2-7ish: Same deal as day 1 through this time (as far as mom's part and your part), but they will be developing fur throughout this time. Their eyes will be closed, ears will be closed and do not typically open during the first week. They are basically popcorn at this age and when you go to check on them in the nest, they will likely pop and hop in random directions as soon as they feel the air (this is normal and important for muscle and bone development), just make sure that when you are done, they are back in the nest and warm.
DAY 7-14: This is when the fur really starts coming in and they get to a point where they can regulate their temperature better. Eyes will open and ears too and it is really important (in my opinion anyway) to handle them daily at this time. The last thing you want is a show rabbit who tries to fly when a judge touches him, and this is the time they can learn to kind of trust people. They can be out of the nest some especially later in the week and will be learning to hop effectively and with purpose. Once they eyes are open you will want to check eyes daily to ensure they do not get infected. Nest box eye is common due to them peeing where they sleep at this age.
DAY 15-21: At some point in this week, you will notice them eating hay, this is the time to really start checking butts daily. With the diet change they can get wet/sticky poops that need to be cleaned up as soon as possible to avoid infection or other issues). Also, if your baby has sticky poops, a bit of probios could be helpful. The babies are at an age where they just do what they want, chase mom down to eat whenever they want and if they can, sneak out of the cage and explore, so be aware of that and watch your step. This is an easy age because your only daily task is to check their eyes and butts and clean/treat as needed.
DAY 22-28: Same thing as the week before for the most part, but believe it or not, by the end of this week, they can be just fine without mom. They are considered fully weaned at 4 weeks old. Most breeders like to leave babies in with mom for 6-8 weeks for maximizing health, but if you have a mom who starts getting aggressive towards her babies after 4 weeks, if they are healthy babies, they will be able to survive without her.
FALSE PREGNANCIES: False pregnancies can happen, and it is just hormonal confusion for the doe after an unsuccessful mating. If your rabbit starts making a nest about 20 days or less after a mating, she is almost certainly having a false pregnancy. Just let her make her nest and get it out of her system and she will go back to normal shortly after. You can breed her again any time after her nesting behavior stops.
PEANUTS: In any and all dwarf breeds, peanuts happen. This is not something breeders of non-dwarf breeds deal with at all but since Holland Lops who are showable have one copy of the dwarf gene, it does impact their breeding. There are 3 types of babies born in dwarf breeds; False Dwarf (or "Normals"), True Dwarf Rabbits (showable Holland Lops) or peanuts (Lethal Dwarf). If you breed 2 false dwarf Holland Lops together, or one showable Holland Lop to a false dwarf you will never get a peanut, however, breeding 2 showable (true dwarf) Holland Lops together will lead to about 25% peanuts which will ALL die, typically within the first few days after birth. My understanding is that the organs cannot be formed properly in a lethal dwarf, making them incompatible with life. Peanuts are very noticeably different from a true dwarf for a false dwarf newborn, with very tiny ears and a much smaller overall size. It is important to decide what you plan to do with any peanuts prior to working on a breeding program with a dwarf breed. Here, they are used as snake food for a snake we rescued many years ago. Some breeders donate to reptile rescues (usually frozen).
CULLING: Another thing you need to consider before ever breeding any animal, is what you will do with any offspring you cannot sell. The market for any pet flexes often and there are times where there is just not enough demand for the amount of animals out there, so it is important to consider what you will do in those instances. Will you keep all of the babies? If the answer is anything but a resounding YES, then you need to consider culling. Some breeders cull their own rabbits and use the meat for themselves or their dogs, but if you are like me and unable to do it yourself, you have a few options. You can sell to a cull buyer, a reptile store or rescue or (what we do here), Donate to a zoo or bird of prey rescue. I would encourage anyone to not waste the meat of your culls, as so many places could use it.
I am really hoping to one day get a day to day photo album showing how a litter grows from birth to at least 4 weeks old, but so far I have not had that kind of commitment to pictures.
