Yesterday I was out in the run with my chicks... they are a little over a month old. I have them in a Chick-n-hutch with a liftable lid. I had opened the lid and they had all three jumped out onto the edges of the hutch.... and a big gust of wind caught the lid and slammed it down on all three chicks. Now, almost 24 hrs later they SEEM ok... Kiko the white cochin took the worst of it I think... for a few hours yesterday she would hunker down to the floor of the hutch and one eye would drift closed. She just wasn't acting right. She seems to be doing much better now, and the other two never seemed to show any ill effects... But then again, I've never really had chickens before.. and I am not sure what to look for. At the time of the accident I caught them all and inspected them. No signs of broken bones, no cuts, no blood... nothing like that. The wind slammed the lid down on them so fast I didnt have a chance to catch it, and I half expected to see severed chicken parts. I find it hard to believe they came out it unharmed... but am grateful they appear to have done so.
