Hello! I have two adult girls. Two that are 4weeks old and two that are days old. How soon can the middle girls live with the adults. ( I'm already putting them I'm the yard in their own run during the day) and can I keep her babies and the middles together in the same brooding box?
In warm climates or during the summer, chicks can be without heat at 6 weeks old. In cold weather I keep a little extra heat for them until 2 months old. When you add yours in with the hens it would be a good idea to give the babies a place to escape to if the hens bother them. My rule of thumb.... don't put little ones together who are more than 3 weeks difference in age.
I did two groups of chickens last spring/summer, about 2 months age difference between groups. They didn't start to integrate until I began placing them in the coop with the older birds at night. Even today one rooster and two of his hens wont go in in the coop at all unless I put them in there, they sleep with the duck instead.
