I had three rabbits in an outside cage, I have had them for while and never had babies. So, imagine my surprise this morning when I went out to feed them and there were 3 babies. 2 had passed already, I brought the reaming one inside and warmed up on the heating pad. I am not sure who mom is? They both have pulled their fur, one has a swollen genital area, and I can feel her nipples clearly through the fur. Am I assuming correctly? Help, please!
