Same as everyone else...no. I brood my chicks in a separate pen in the coop with the big girls. But they are separated by a framed, wire covered pen form the big girls...looky, no touchy.
I don't even THINK about integrating the flock until the chicks have basically outgrown the brooder...because by then the chicks are about the same size as the hens. Then we do a few days of everyone in the pasture and run together, plenty of room to run away if one is tormenting another. Remember, there WILL be a pecking order no matter what you do. My teenage daughter hates to see them fight so she will usually let them free range together on a weekend day when she sits out in a lawn chair and squirts any aggressive old hens with the hose if they are mercilessly picking on a young bird. For the first few days the younger ones will return to the brooder at night, where I have left a panel open for them to enter. After a few days the young ones will begin exploring the nest boxes (when there's not a hen around!) and jumping up on the roosts to try them out. After about one week I leave the brooder panel open and they can choose where to sleep. Generally within 2 weeks everyone is up on the roosts. If I bring a new chicken into the flock, after quarantine and time to integrate, I wait until dark and then put the new full-grown bird on the roost in the dark with the rest of the flock. I've never had any problems with this.
