We have 15 CX--this is our first run with chickens, and with meatbirds. They are almost 8 weeks old--we had planned on butchering this weekend, as they are all between 7 and 8 lbs. This morning I went out to feed them, and noticed one getting trampled. He is sitting with one leg fully extended, and can't/won't stand on his own. I moved him to a separate area, and gave access to water, but I'm not sure what is wrong with him. My husband said we'll butcher him tonight--which works fine, but it would be nice to know what happened to the little (big!) guy. My husband rotated both legs fully--and they don't appear to be broken. Any idea what went wrong?? Thanks so much for any advice!
