Since last Wednesday (15th) one of my buns, William, has been moulting like a mad thing! It's mainly from around his hips and the base of his spine just above his tail. He's not keen on being handled, but I got him brushed a little over breakfast yesterday - today it's coming out in loose chunks that I was removing with my fingers! He doesn't seem disturbed by this, and I can't see anything untoward on his skin (also still eating, drinking, steady weight etc.). Is it normal for buns to be moulting so much now? Both he and his brother Jack are short-haired, but Jack isn't moulting at all? William doesn't do well at the vets, so I thought I'd see if this was bog-standard rabbitness before stressing him unnecessarily.
