I'm sure it's probably been asked and answered elsewhere.... I have a one year old barred rock rooster, and some new chicks, they are three weeks old and still in the brooder. The Question: how old do ya'll recommend your chicks be, before introducing them to a mature rooster? I am getting him a year old hen today, as he is definitely lonely, but I don't want to intro the newbies and have him be aggressive towards them. He hasn't shown any signs of that yet, but I'd hate to lose a new egg layer before they start producing... Thanks, Ben and Kayla!
