My 4 year old rooster has been losing coordination for the last year. Several times lately I have found him laying down and unable to get back on his feet. He walks fine once I stand him up. Last night I found him laying on his side, feet kicking, eyes closed and what looked like death on his face. I stroked his side and he laid still. I was ready to go get the shovel and bury him when all of a sudden he lifted his head like he had just woke up. I set him on his feet and he walked normally back into the coop. I realize I will probably lose him but I am curious what his problem could be?
