Hello all! I am brand spankin new here and have tons of questions, but the most concerning right now is this: I purchased 10, 14 month old Production Reds a week ago. They all looked great, had all of their feathers, and seemed happy and healthy. Today I noticed that all of them are missing their feathers on the front of their necks. Just above the breast area. The empty spots are about an inch wide strip. They are eating great--laying hens crumbles, fresh fruits and veggies, and they adore plain yogurt with reice crispies in it. There are quite a few feathers laying around, but I have not caught if they are doing it themselves or to each other yet. I use food grade DE in the coop and run area, especially this week as they have not had a dry day until today and their area just stayed wet and miserable. The coop stays dry though. I appreciate any help you all can give me. Thanks a bunch!
