We started with two barred rock and one RIR. At 6 weeks old we moved the trio out to their coop and run. The RIR turned out to be a rooster so sadly, he had to go. It was just the two big girls. In the meantime, we got a Buff Orpington, a brown leghorn and a white leghorn chick. They are now 6 weeks old the two BR are 11 weeks old, older, but not yet laying hens. Still, they are being bullies! (I'd use another "b" word, but won't). The three young ones stay in the coop all day, with food and water, because the older ones chase them when they come out. When do they all just get along? What can we do to help these two groups become one?
