How to identify the mother bunny among multiple females with babies?

I am not sure if you bought all the rabbits together and were told they were all females, or if you accidentally bought a pregnant rabbit, or if you mated her. This may sound silly, but you should make sure that all the rabbits are female, because if there is a male in the cage, he needs to be separated from the females and the babies. Nursing mothers are very secretive, and usually only nurse once or twice a day. They only do so when they feel safe, usually just before dawn and/or just after dusk. It's unlikely you will catch the mother nursing, so that can't be used as a clue. Rabbits who are about to give birth will pull their fur out to make a nest. If any of the female rabbits are missing fur, she is likely the mother. Should you have one male in there accidentally and two females, they both could have had babies. In that case, the male should be separated, and the mothers can stay together because it will be impossible to tell which baby belongs to which rabbit. Just make sure the cage is extra large so they both have plenty of room for their nests.
