do bunnys molt when

my two male bunnys have lost thier bond due to being apart at the vet when nuetered, they apart at the moment till the hormones die down and i can try bond them. I bring them out every night to have a run round on the my sofa bed which is neutral. they had a scuffle tonight and when we pulled them apart noticed some fur on the sofa. has this been pulled out or do they sometimes molt when fighting.... sorry for the stupid question

When rabbits fight it's one of the things they do. They pull each others fur out.

As long as they don't have any large cuts or wounds I wouldn't worry about it. It doesn't hurt them if they lose a little fur.

I would keep them apart for a while longer though.
