Looking for some advice here... We never had chickens until about 1 month ago. Someone split their established flock and we have 1 auracuana roo and a few hens. We have a large coop for 10-12 birds (wyandotts or so), which is completely enclosed/shingled/new/etc. So here's where things get weird. Our roo started seeming weak, I being a novice thought maybe I was crazy so I watched him and felt after two more days my concerns were validated. I checked him over and found evidence of lice (egg packs on his feather bases around his head) and saw one scurrying about near his head. He is having a hard time walking around - it's getting better but he's still ataxic - stumbling, uncoordinated/weak. He is eating/drinking/scratching for bugs and scratch like a champ. Normal stools. No one else had live. I dusted them all and changed the shavings out of the coop and even dusted the coop. The ladies are okay but are still not laying. And, everyone seems to be molting. I just found out the roo had some previous issues of weakness but I wasn't able to find out what. The roo is very very thin. But again he's eating well. Any thoughts?
