I have a year and a half old cochin rooster. he is my top boy. I found him sitting on the floor of the coop, unable to stand or keep his balance. He tilts his head to the right side and back. His crop is empty and his breathing is at times labored, not all the the time, but at times. he was fine at 430pm and I found him at 10. No mites that I can see. No other chickens that are showing any similar signs at this time. I'm going to give him some vit water and yoguart. What might this be and what should I do? Anything will help. Of all the chickens I have, this is the one that will break my heart if he's gone tomorrow. But of course that's how it always is. Thanks!
