I have a rooster that is 8mo old, he is a standard polish, he is a hatchery bird that we got at a feed store. He only has one wing, the other never grew feathers and seem stunted. This morning we found him laying on the floor of the coop unable to get up. He still seems to have streangth and able to move his legs when I pick him up. When I put him on the ground he just falls over. While holding him he was gasping, opening his mouth wide and streatching out his neck. He has a little discharge, non that is very apparent. Just a little gunk around his mouth, his eyes are clear as well as his nose. He is shaking his head. He is in a flock of 18 layers, I have seperated him from them. None of the other chickens are showing symptoms. However I did have a silkie that went to show and was showing the gasping symptoms but nothing else during the show. Could it be mycoplasmosis? or something else?? I am worried about the rest of my flock!
