I have 2 existing flocks of chickens. I have 4 bantam hens, approximately 5 months old, that have their own small coop and run. I would like to integrate them in to the big coop with my other 16 large fowl hens. They are all a year old or less. All of the chickens have free ranged together in my back yard several times a week with no major problems. I'm worried that they may gang up on the little girls if in the coop and run together. Does anyone have any suggestions on how to safely do this?
