I'll keep them inside for a few weeks. Right now they're in my office with a heat lamp on them. In a week or two I'll move them out to the chicken coop. I have a bigger pen I can put them in out there, but I may just let them run loose inside it. After about few more weeks I'll let them out into the chicken pen. Once they can get out of that they'll be on their own.

The two older hens I have will chase them off if they get close, but they won't kill them. They seldom even go in the coop anymore. One lays her eggs in there, and the other mostly lays them somewhere else. Sometimes I find them, sometime I don't. They both roost together in one of a few different Cedar trees in the barnyard and only roost in the coop when it's really cold or stormy.

I'm hoping the new chickens will keep roosting in the coop.
