Yesterday I found one of my chickens standing at the front of one of the nest boxes. Her head was all bloody from the chicken inside that is broody won’t let her in. Is that normal? I don’t understand since there are a lot of other boxes available. I now have the injured one inside in a crate. Now I have to find out how to heal her poor bloody head. I’m so sad for her! Sorry for the yucky picture but need help!
