I have a young buck that has almost completely lost his baby coat, has grown guard hair but has not regrown any sort of undercoat. I've never seen a rabbit that looked like this. The hair lies flat against his body and it took a while for me to get used to looking at him because at a glance he looks thin - he isn't. Have any of you seen something like that? Is it common? I'll try to post a pic over the weekend.
