Ages would be good to know,,,
I hatch inside and brood outside in a brood house, it has its own run with chick wire. My littles go in at 2-3 days old, they can see but not touch or be touched by the big girls. They get regular visits from the flock (my girls luv to see chicks), and there they stay until they are 5 weeks old. At 5 weeks they are fully feathered out and ready to go (off of heat @ 4 weeks and roosting), even in the winter. They are moved to the main coop at night, and watched the next AM.
This is when they meet the "Queen" (my oldest hen) and she lets them know who the boss is, the rooster stands back and watches.
I provide a get away area with 3"x3" fencing around it, food in it, extra water nearby (until they find the main source). There are many hiding places for them as well, perches for them to get up on. Also my rooster will feed them just like he does with his hens.
After a week they are just another bird in the flock. I keep the get away area set up until they (at least the biggest ones) can no longer fit through the openings. By this time they know who they can be around and who to avoid (that big blue bird).
