So I've noticed yesterday that my beautiful guy was lethargic. I've seperated him, dusted for fleas and mites. Cleaned his fluff which was pretty full of poop. He's been given electrolytes and is in a warm heated garage. He's new to my flock, we've had him maybe three weeks. What could this be? Would pasty butt make him inactive. Like not moving, barely opening his eyes. I should add that he HAS pepped up quite a bit today, walked around a little and is making noises. I'm bringing him warm oatmeal in a minute too. Any insight is appreciated!
