Okay, y'all chicken experts... I need your help. I went down to check on my chicks today and found Carey, a Partridge Chantecler, on his last gasps, flat on the brooder floor and unable to stand or hold his head up. He kept moving his legs like he was trying to stand but they weren't really connected to the rest of him... Like how you feel when you try to walk after you have a hard fall, if that makes sense. I checked him over... Nothing physically wrong, that I could tell, major bones intact and body condition good. His crop was empty, which was odd, and when I prodded his crop and neck to feel if there was anything broke he vomited up clear liquid. He died five minutes after that. The liquid had no smell, it was just clear water. The other two chicks in the same brooder were the same as usual... Bouncy little brats clamoring at the door to be let out. He was normal last night, active, eating, drinking... And gone this morning. Bedding is pine shavings, like all the rest of my chickens have. They're in my basement, but off heat. Feed is un-medicated chick crumble, and they have clean water to drink. I thought of choking, but I couldn't feel any blockage in the neck and he was breathing, just limp. This really has me puzzled. Anyone know of something that would have caused this? Thank you.
