Daughter got 2 male bunnies in the spring. They were not friends, but after living together in the same hutch with a divider screen down the middle for months we tried them together. One established dominance and now they don't fight and snuggle together. Don't see any problems between them. But the less dominant has gotten skinny. Checked out good at the vet, no worms, etc. Could the other one be keeping him from eating??
