We thought my friends chickens were molting about 1 month ago. They are only 9 months old. I went to see them today and 2 of the 3 hens are bald behind their head on their necks. Are they still molting? Could the rooster be pulling them out? Mites? How long do chickens molt? The hens hardly layed for the last 1 1/2 months and now they are back to laying again, but where did their neck feathers go????
