Hello, My two rabbits had three babies earlier this year Just today I noticed that all three of the kids (almost three months old) have some bald spots on their backs. Two of them have some strange, clumpy, black spots in the bald areas. After observing them, I've found that the mother rabbit was pulling and chewing on the kids' fur. The kids are also licking themselves and each other on the bald spots. I don't think I saw the black spots on them before but my guess is that the black spots are their baby skin. I am very concerned about the bald spots. What do I do? Why is the mother rabbit pulling their fur?
