we have a flock of 6 big hens. 3 are barred rocks, black and aggressive, 3 are somthing else, yellow and sweet. We got 4 babies over 4 months ago from a local swap meet. This weekend we relized two were roosters so they got a new home. We have had the babies in a see but dont touch layout with them having a seprate space, cage and run where the big chicks can watch but not attack. Last night we tried puttting the babies out with the big ones. The black ones attacked! Aftr this I poped the yellow ones in the baby run and all went well. How do I get all 8 in the big heated coop as one flock before winter?
