Hello, we have to neutered male rabbits. We got them when they were 8 weeks and 10 weeks old. They are just over a year old. They bonded great and have been great bunnies. Yesterday morning my son found them fighting. Hair was everywhere and there was blood on the carpet. He got them separated. We created a pen inside their large enclosure. Monitored them all yesterday and much of today. They were laying up against each other. We are now trying to reintroduce and rebound them. Brought up a small pen and put them in our kitchen. They won't move from the litter box. The black one (Charlie) has been grooming Chester (white one) which is a good sign. Chester though seems quite anxious and scared at times. We have tried feeding them together but they won't get out of the box. Also Charlie's nose doesn't look the best. Anything I should do? Any suggestions would be great. We are pretty new to bunnies and we're shocked that they could start fighting after a year together. We were planning on leaving them in this small enclosure for a couple hours and then back into their bigger pen (it's a large open gated space with a big box they can go into, toy, litter box etc. ). If we don't see any aggression in this small enclosure should they be ok again?
