I have a red sex link hen that is acting very odd. She, nor her "sister" has laid an egg in quite a few months. The one in particular has feathers missing from her back and tail, and her comb has shrunk. She either lays in the coop, or spends the whole day in the front yard picking at bird seed while the others forage all day. At night, she slowly makes her way to the coop.... except tonight.... she chose to sleep under the carport. :/ She is usually quite noisy, but lately she has been very quite, and seems to be in her own world. Is she molting? Will she be okay?
