Hello! Our son is raising rabbits and his doe had her first litter this weekend. It was a little odd though. She delivered one very fat baby on Friday evening in her nesting box. She hadn't prepared it at all. The next evening she started pulling her fur out and building a new nest in the corner of her pen. We moved the baby bunny to the new nest and came back and checked her 30 minutes later and there were 7 new babies plus the first one. Any thoughts on why this happened? They're all doing fine and she's a great mother.
