I did a search on this topic but couldn't find anything, probably because it's common knowledge for all you experienced folks. I have a nine or ten week old EE with a bald neck patch who is continuing to lose feathers. He seems to scratch and fluff quite a bit, too, and the feathers he loses have pockmarked-looking shafts. The area around the bald patch has a little bit of brown discoloration, but I don't see any distinct wounds or scabs. His skin looks a little pink. I haven't caught any feather picking, but there is definitely some conflict, flaring, and flying at each other during free range time in the evening. I'd like to treat everyone in the coop tonight with poultry dust just in case it's not feather picking or genetics, but I don't know if would be bad for them at this age. I posted the pics from last week just in case they help. The pink skin, slight discoloration and incresaed bare area have happened this week, so they're not visible. Thank you!
