Hi, I have 7 chickens in total. 3 of these chickens have bald areas on their sholders on 1 or both wings. This has been going on for a couple of months now. Skin area is pink and not bloody. We thought this was molting but now not so sure. They look like there are new feathers coming and other areas of their bodies seem fuller and fluffier with feathers but all I have read says they only moult in end of Summer/Autumn and here in New Zealand we are in Summer (and as I say...this has been going on for a couple of months now.)?? Egg production is non exsistant. they are approx 18 months old. What does anyone think?? All advice appreciated.
