I have an 18 week old cockerel who is a bully. I have hatched 5 eggs, unfortunately 3 are cockerels and 2 hens. I am looking for new homes for 2 of the cockerels as they are beginning to fight. In the meantime the main cockerel is becoming a bully and tonight I’ve found him in the coop and the other 4 12 foot high up in the walnut tree roosting. Is this normal please?
