I pity-purchased a really lovely bantam cochin roo in early November (I was already getting a standard trio from the breeder, she offered me the little guy as an alternative to the soup pot, and I am a sucker), and he was well into his moult at that point. Three months later and his hackles are still encased in sheaths almost as much as they were in November. This is the first time I have had a chicken take this long to shed the feather sheath, is there something I should be doing?
