I have a young, 6 or 7 month old bantam mixed breed rooster. He lives with 8 hens. He's always walked somewhat funny. I figured it was because he had oddly shaped feet. That may still be the case. I later thought it was because he had worms. Not sure if he did or not, but I gave him medicine three times at 10 day intervals. He would sometimes stumble and fall, sometimes would fall backwards for seemingly no reason. Again, I figured it was because his feet are weird and his back toe doesn't quite come straight out like it should. He was actually doing relatively well as of late and I figured I'd gotten all the worms. I went out this afternoon to feed them and found him standing in the freezing cold with his eyes shut and his head down. He didn't bother to look at me until I talked loudly. And then he just shut his eyes again. He didn't bother moving when I came in the run or when the hens ran into him. I thought maybe he was just really cold so I put him in the coop, but the way he was acting was just so odd, so I decided to bring him into the house instead. I set him in the bathroom and he just stood there. He isn't holding his wings or tail up. His wings are touching the ground and he can't seem to hold his head up. It just keeps falling forward and he has his eyes closed. He seems to be shaking now, but he's sitting and his beak is on the ground as he moves his head around. Every now and again he'll make a sucking noise like he is trying to get air. His nostrils are clear and there is nothing coming out of his eyes. His poop is extremely runny, basically just brown water. I have not found any visible wounds or issues. I set food and water nearby for him. The way he was acting, I really thought I was going to watch him die when I brought him in the house. It's been two hours now and nothing has changed. When I go into the bathroom to check on him, he looks up at me for a while but then it is as though he cannot keep his head up or his eyes open and he'll blink slowly and shut his eyes and then his head will slowly go down again. No other bird is showing any of these symptoms and they are all very active currently. I really don't know what else to do with him or even what the problem could be. Any help?
