Good day to you all ! I am looking for help why my girls butt feathers are not growing back . They lost them 3 months back . I see no mites or lice but I will look somemore . I gave them milk , cat food, and fish for more protein . Did not seem to help . Free rangeing the last month brought back the feathers on there backs . I feel that was from molting, but there "butts " show no signs of coming back. I took a picture today so you all could see ,mind you it's hard to get when they know you're looking . Thanks Reg.
