I have a young buff orp that was born in June. It is either her or her sister that just started laying eggs. She has lost many feathers in an area on her back between her wings and lower neck. The area is still covered by down for the most part. This started a week or two ago and she has not lost feathers anywhere else. She does appear very healthy and acts normally. I also have a 10 month old wellsummer that stopped laying eggs and is losing feathers on her neck. Not too worried about her or should I be? Don't they start molting on the top of their neck and it gradually works down? I should add that I also have a young rooster, same age as the buff orp and he has started mounting the hens. He is very gentle though believe it or not and is not aggressive. None of the other hens are losing feathers. At what age and what time of year do most hens molt? Thanks
