I have two sibling baby rabbits and a lop rabbit. The lop rabbit is like 2-3 months old already. I put her to the two baby rabbit's cage. When one of the baby tried to sniff her, the lop chased the baby rabbit around the cage but stopped. I separated them immediately. But i don't know if they are just playing or fighting. Should I just leave three of them together so they can get along? Are they playing or fighting? How can I know?
