My elderly bantam cochin hatched 3 Easter Eggers from a different hen. They are now 15 weeks and one is a cockerel who keeps trying to breed with his 9 year old adoptive mom. I have sectioned off the coop to separate them and only allow supervised visits when they free range and I am sitting there to yell at him. At night he screams and fights with his 2 sisters because he no longer gets to roost with her.I have Jasper with his 2 sisters and Pee wee(the mother hen)with an adult rode island red at night.
