Ok, lost my cornish rock roo last night. Thought maybe a dog had got him but no signs of attack. I was reading a random thread on BYC that suggested flip-over disease. Well I was just wondering if it would be possible for a 7 month old roo to suffer from this. I have 3 other hens I got with him and they are doing fine. He wasn't fat or overweight, in very good shape actually. When I found him this morning he was lying by the gate on his back with one foot up in the air. No other chickens are sick (have been battling fowl pox but he had shown no signs of the wet form). So should I just dismiss this as flip-over or should I be concerned with something else? Oh, they are on Purena Layena 16% pellets and are in a fenced-in area with lots of grass. If anyone could help ease my mind, I would greatly appreciate it. Thanks!
