My little flock of 4 pullets and one cockerel (was supposed to be a pullet) are around 16-17 weeks old. The boy has started to try to crow and I think he attacked one of the girls this morning. They are locked in a coop at night and free range during the day. This morning the girls came running out and I saw my Barred Rocks bloody neck with missing feathers right away. I cleaned her up and blue-koted the injury and she was fine all day, no one bothered her. I am assuming the young boy tried to mate with her this morning and was too rough? Both my Barred were getting more red combs and looking like they are ready to lay, but after today, the colors dulled and went back to yellow- are they traumatized? Should I just lock them up like normal tonight and see what happens tomorrow? I did not see any aggressive behavior today and was home all day. I am trying to figure out how to increase my hen/roo ratio but afraid to bring in outside hens, I just want everyone to be happy but that little roo better be nice to the girls!
