Greetings from College Station, Texas. Our chickens are free range, so I can only speak from that experience. When our 5 peeps were 2-3 weeks old, we let them forage along with the others. The peeps stayed in a group and did pretty well. They were at the bottom of the pecking order, of course, whenever we put food out for the chickens. That was about 18 months ago, and 2 of those original 5 are still with us. They are Easter Eggers, and have been good sturdy hens. One has already hatched peeps of her own. Good luck with yours.
