I will be moving two of my chicks into the coop today. The RIR and BJG are 6 weeks old today. They have been living with 6 other chicks, 3 Ameraucaunas, and 3 buff orps. The Ameraucaunas will be moving in too as they have a lot more feathers then the buff orps who will be moving in next week. My question is about when do I feed the chicks in the coop regular chicken food instead of chick starter?
