my chicks just hatched on saturday-monday. i was wondering at what age can i let my chicks go in the coop/run with my adult hens. the coop is a coop/run, it about 8' x 16'. my chicks are divided in the coop/run with the mom and the other adult hens. it's 1 BO and 2 RIR, and 2 OEGB chicks are about 3-4 months old.
