I have 4 big hens, 6 months old and two littler ones, 4 months old. They all live together now in the coop and in the run. But every day I see a big bullie one of the littles. The Americauna sticks up for herself most of the time but the RIR, is so scared all the time. I love them all, but when or will they ever be one happy group or will it always be two groups?
