I have two seperate coops that connect w/ a little "chicken" door. One coop is larger and contains only 3 chickens, 1 layer hen and a silkie pair. The second, much smaller, contains 4 young layer hens. If I were to open up the little door and let them together, which would make many things a lot easier for me, would the silkie roo "attack" the "new" hens????
