He and my other chantecler roo got into a fight between a fence. He lost a spur. A couple of days later he started favouring his other leg. I couldn't find anything wrong with it. A few days after that he just lay down. I've had him isolated for 2 weeks now, giving him warm baths. He wouldn't eat or drink unless I hand fed him bread that I soaked in antibiotics (I was thinking that if the leg had some kind of infection I'd knock it out that way). I had already figured I'd have to cull him, he just beat me to it.
