My barred rock rooster is 5 months old, no injuries that I've known of, has a good quality diet, and is growing well. In the last week, his wing feathers have started sticking out from his body. Someone told me it's angel wing, but I thought that was only in ducks. He came from a reputable local breeder, the 4 pullets that I got from the same place with him are all developing normally, and I can't figure out what is causing this. He acts like his normal self, just looks a little odd. I plan on breeding, so I'm trying to figure out if this is genetic and I need a new rooster or if I can fix it. I can really use some help here and appreciate any insight and advice!
