My Buff Orp Dandelion is loosing feathers around her comb. At first it was just a little bit, then it got bigger and several other chickens have lost some around there too. On dandelion I have also seen some down feathers coming off too, seeing them around the coop and she isn't quite as fluffy. She is in the middle of the pecking order. Oh, my two wyandottes are pretty mean, they might be picking on everybody. They are a little over 9 months, is that old enough to molt?
