Hi Everyone, I have 9 pullets, 5 of them are 9 months old and 4 of them are about 6 months old but they have never molted before. When will they molt? Also, two of the 9 month olds (both black SL) are missing feathers on their back, but they never grow back so i don't know what the problem is there (we don't have any roosters) . I will try to get some pictures ASAP of them so we can figure out their problem. Thanks for the help!
