My chickens reside in a pole barn at night & during inclement weather. They have run of property otherwise. Currently have 3 RIReds, 2 Silkies, 2 Americanas & 1 Barbed Rock. One of the reds started losing feathers like crazy. She appears normal otherwise. I don't c anything but this is first experience w/this. She looks real shabby. She is @ 1 1/2 yr old. She has patches of skin where u see holes where feathers were. So far none of the others are losing feathers. Read @ molting. Her loss was in an order except she did not lose head feathers. Live in Chicago area so have that weather. Looking for advice or suggestions. If it is molting is anything done to protect exposed skin? Thank you.
