I got 9 chicks yesterday from a local farm, they are 2 weeks old. One of the barred rocks is pecking its own bottom, it is bare about the size of a nickel. I have also noticed some rust-colored poo, not sure if it is blood or not. They were not on medicated feed for the first two weeks, so I am going to get some at agway this morning just to be safe. Does anyone know what the pecking of the butt might be a sign/symptom of? Otherwise that chick as well as the others look pretty good, they are responsive and walking around, eating and drinking well as far as I can see. I have 9 chicks in a box about 3x5 with wood shavings, a few small branches for roosting, clean & elevated food & water, temp under the light is about 85-88. thanks!
