So I found out that my rooster had lice so I've been treating him, the coop, and the rest of the flock just in case. I've been using manna pro poultry protector, a home made spray, and sprinkled some diatomaceous earth everywhere. I have only seen lice on him but I'm still treating everyone just in case and it's my first time dealing with it. What's worrying me is that his skin almost looks worse? I found the lice because he went to do his lady dance and I saw his butt looked red so I nabbed him and the skin all around his vent looked red. I just checked today and i can't see any lice anymore at all but his skin is still heavily red and irritated and it even goes up to his mid "stomach" area. Is there anything that I can put on his skin to help? And how long will it take for him to get back to normal?
