Agreed. Depends also if your older girls are laying age or not. Much easier to integrate if they are not.You would have to integrate them. But yes, they are ready. Some people just put them in and have no problems. However, I like to use the see no touch method for at least a week. I place a crate or a prefab coop in my larger coop. Thats where the new additions go. That way, they learn where their coop is and the flock can get used to them.
