I am too lazy to look up, but do roosters molt similar to the hens. My roosters is losing lots of neck feathers, he looks kind of pathetic. Thinking back, he lost all of the long tail feathers 3-4 mths ago. He may be regrowing those slowly. Looking up close, there are new feathers coming out at the neck. Glancing at him, I dont see any thing crawling around on his skin.
