My rooster is not acting right at all! He is an EE and I didn't add any new chickens to my flock. Yesterday is when I noticed that he just stands around and didn't eat at all. He isn't even a year old. When he walks he sort of losses his balance. He's been throwing up and it smells really bad. It looks like he has diarrhea too. His comb is dark and off color. We aren't around any other chickens or anything. Could he just have some sort of sickness that will go away? I need him for my breeding next year so I hope he makes it. I have him separated from all the rest now. Any help would be very much appreciated!
