I've got a large breed chicken (at least part Jersey Giant) that feels like he's got a deformed keel bone. I'm still guessing that he's not a she because while he's 5.5 months old and no crow yet, he matured VERY quickly as far as size and comb and I'm seeing signs of spurs on his legs. I would really like to keep him as long as he stays quiet like now but he's having some problems. Plus, he's special because he's one of two chicks we've hatched out on our own. We had a hen go broody on 14 eggs 2.5 weeks AFTER we got rid of the two roosters we had before. He used to be able to get onto the perch that's about 3 feet off the ground...hop onto the lower perch then up to the top. Recently I picked him up and noticed his keel bone feels like it's inverted. Could it have gotten broken when he jumped or got pushed off? He's not very high in the pecking order of a 19 bird flock and he's the only boy. About 6 weeks ago I saw him bedding down in the nest area and thought with high hopes that he was, after all a she but with the appearance of spurs that hope is gone. Now that I think back, this was probably when he would have gotten injured (on his 4 month birthday). He was fine getting up before that. This morning, I went out and the other chickens had forced him crookedly into a corner so they could use the nest and I had to get him out. He was limping some but worked the stiffness out. He wouldn't eat from the food dish but would from my hand..until another chicken tried to eat from my hand. He does feel a little lighter than normal today as well. Anything I can do for my poor guy? I'd rather not cull him since we decided not to do meat birds because the kids aren't emotionally ready for that yet. I also don't want him to suffer needlessly.
