Im guessing my hens are going through their first molt, but I'm not seeing any new feather growth. One of my hens has had a bald butt for several months now. Skin looks healthy, they don't look like any of the pictures I've seen of molts before. Their feathers are very fuzzy, they have bald spots everywhere, but not seeing any new feathers coming out. What is going on???? Hens are about a year old, 15 hens in a 12 x 12 coop with a 12 x 30 ft run. Help here, I've been supplementing with mealworms, cat food, and they seem healthy otherwise.
