Last night my Black Polish rooster attacked my Black Polish cockerel to the point that his head was bloody. Today he has been sleeping most of the day and seems very wobbly on his feet. He keeps bobbing his head up and down when standing. Could the rooster have caused some brain damage and if so, what do I do? We are putting up a new pen for the rooster because I don't want him around any of the chickens now but I can't get rid of him because he is my granddaughters pet. Ugh!!
