I know they molt,(this is our second Autumn with her,last year she was still growing and didn't seem to molt)but she is shedding feathers all over the place,it looks like a fox-attack, and she now has big bald patches appearing too-is this ok or should she see the vet? She isn't laying now,but is perky and fine,possibly her comb looks slightly less red.She is a bantam wyandotte.My other hen seems not to be molting at all.
