Each litter can contain between one and 12 babies, with the average being five. And female rabbits can get pregnant again almost immediately after giving birth. When you consider that the babies of each litter can begin reproducing so soon after they are born, the math can quickly become overwhelming. However, the potential for a surging rabbit population because of their prolific breeding is greater than what happens in actuality because of a few factors.
Most notably, about 44 percent of cottontail rabbits die in their first month of life, according to the Missouri Department of Conservation. Only 20 percent to 25 percent live for a year after birth. That means many rabbits never produce offspring of their own. One reason rabbits have become infamous for their ability to produce so many offspring may be because of a well-known math problem involving the Fibonacci sequence that dates back to , according to Live Science.
In a book on mathematics, mathematician Leonardo Pisano Bigollo, who later came to be known as Leonardo Fibonacci, posed a brain-teasing question along these lines: A male and a female rabbit are placed in an enclosed area. After a month, they mature and produce a litter with one male and one female. That pair then goes on to have another litter and so on. If YES , if the rabbit is larger than a softball and weighs more than 4 ounces or grams, it is on its own and does not need human intervention.
You will not see a lot of activity at the nest; mother rabbits stay away to avoid leading predators to the nest. If you do suspect the nest is abandoned, lay four pieces of string or twigs in a tic-tac-toe pattern over the nest as straight as you possibly can.
Leave the area and check back in 12 hours. The babies should be taken immediately to a state permitted small mammal rehabilitator in your area. A Word About Mowing It's a good idea to check your yard before you mow; because rabbits are in shallow nests, it's easy to mow the "top" off of their nest, possibly injuring babies. Remember … Never chase a rabbit to capture it. The stress of being chased can be dangerous to a baby rabbit.
Rabbits are a high-stress species prone to a condition called capture myopathy, which is caused by chase and stress. Rabbits sexually mature between the age of months. An unspayed female bunny can start as early as days old.
Female bunnies are prolific producers and can give birth to a litter monthly because of their short gestation period of only days. This is why it is vital to separate your does from the bucks before the female gives birth to prevent another pregnancy. Most does kindle late at night or in the early morning hours. Some baby rabbits will be stillborn, so be swift to remove and dispose of the dead kits and the placenta soon enough.
She may eat the stillborn rabbits and her placenta to prevent predators from tracking their scent. Lack of a body means no scent, so no predation! Besides stillborn births, some kits can be born weaker than others and may not survive. Female rabbits are not instinctively maternal and may ignore the vulnerably weak and young rabbits. They often prioritize those that are more likely to survive and focus on feeding and nurturing the stronger babies. These animals have innate drives to preserve their species, and stronger kits have higher survival chances to breed themselves eventually.
For this reason, does may separate their kits into two groups where they neglect the weak ones and concentrate on the stronger offsprings. Mother rabbits do not mourn the loss of their newborn kits because they know they can replace them just days later. However, they are overprotective of their surviving offsprings and may react aggressively towards human caregivers who try to handle the babies.
The female will be ready to breed just 24 hours later, and an unneutered male is extremely likely to take this opportunity. Aa rabbit may eat her stillborn babies. Sometimes, a rabbit will also eat her living babies. This is especially likely after her first litter. There are several explanations for this behavior:. A rabbit eating her young is most likely to happen after her first litter.
If a rabbit continues to eat her young after a second or third pregnancy, you should cease breeding her. In this instance, it means your rabbit was not pregnant after all. Phantom pregnancies are common in unspayed rabbits. A rabbit pregnancy lasts for about 30 days. If there is no sign of baby rabbits at this point, she has had a pseudopregnancy.
If the pregnancy was false, a rabbit will eventually stop behaving maternally. She will cease nesting , and become much calmer. A pregnant rabbit will continue with her hormonal actions until she gives birth. There is no absolute rule about how many kittens a rabbit will birth in her first litter. Care for any of her neglected kits. We just discovered two baby rabbits in a large flower pot outside that we were about to plant flowers in.
They seemed very young- so tiny with no hair.
