I have an almost 6 month old rooster who I hatched myself and is very attached to me. When I brought him out to the barn I had him in a chicken pen in the big coop with the main flock. He eventually ran out of head room so I introduced him to a mother hen and 3 month old chick in a 4 hen coop. All was fine as far as nobody getting hurt and the hen and her baby certainly fly well enough to stay out of his way. He has not demonstrated any protective behavior, just kind of uses his rooster power to be selfish with the facility. He chases them randomly and has never shown any sexual behavior at all. Instead of roosting with them at night he hogs the entire upstairs, streches out and makes them go to the downstairs screened part of the coop to sleep at night. How do I encourage my little flock to perch together and stay warm at night?
