First off, 13 month old rhode island red hens, in Minnesota, about a week ago we found blood in the coop other issues: *Chicken 1, Sayde, has been losing tail feathers like crazy, but no visible skin *Both chickens have white dry butts, like chicken poop, not sticky or gooey. So far we have: *Fed yogurt and applesauce mixed with mealworms. They were laying until a week ago, then suddenly stopped. Any ideas? They are apparently too young to be molting, we are very concerned!
