My parents are petrified at the idea of movin our black star chicks out into the coop at 6 weeks. They are afraid the other girls will tear through the plastic netting that is covering the wooden box I got for them and kill the chicks! Do thy have reason to think this? Would the other chickens want to kill the chicks? My dad is talking about building a whole new coop for the chicks now! After a few weeks out with the big girls won't the chicks be fine?
