I recently bought 3 new chicks, a Frizzle, Silkie (4 weeks old) and Jersey Giant (5 weeks old). I haven them in my house, when can I put them in the coop with my other chickens. I have an Americauna and Dominique (almost 3 months old), RIR and Barred Rock (4 1/2 months old) and Buff Orphington (4 months old). I have brought the new chicks out to meet the other chicks and they seem fine together.
