My 12-week old black Ameraucana cockerel, Pete, has a weird feather issue going on. I searched for hours yesterday on BYC on on the 'net and just couldn't find anything - but, I also wasn't sure what to call it! The feathers around his neck appear to not be popping out of the protective shaft they grow from. And, it looks like they are actually breaking off at the end of the shaft part. It's apparently itchy for him, becuase he's picked a bunch out (we've watched him fusshing with them) and now has a bald spot on his neck. I noticed it for the first time Tuesday, tried to figure out what it was yesterday, and since I couldn't find anything online, thought I'd best as you folks for help. He's eating and drinking fine, and is in with 2 other chicks who do not have an issue. They're on Dumor chick grower and I also have them on AV2000 in their water. They are in a large pen in my barn (no access to outdoors yet). I checked thoroughly for mites/fleas, and found none. They do not have access to other animals that could have mites. Here are pics: Any help is greatly appreciated.
