I am the proud owner of 8 new chicks... 4 RIRs, 2 barred rocks, and 2 buff orps. The RIRs and buffs are about 4 weeks and the barred rocks are about 3 weeks. They are chirping away in my bathroom. Coop and run are finished, but I think I'll keep 'em close for a while... sooo proud I think I got everything I wanted from this one breeder, except I'd like to have a couple Australorps. My question is... Would it be okay to add a couple chicks from somewhere else in with these, or would I have to keep them separated? I mean if they were all relatively close in age. I know different flocks have different germs and different immunities, so would the same quarantining be required at this age as it would be if I were introducing a new hen into an existing flock? Thanks!! I gotta get some pics up soon PS. Is it okay to give these chicks grasshoppers and mealworms for treats and can I over treat them with those?
