Hello! I'm new to chickens. About 2 weeks ago I purchased my first 4 hens. 2 are young and not laying yet, and 2 have been laying an egg a day for a week now. I decided to get another hen that was already laying to up my daily egg production, and I built a coop and run that would comfortably hold 5 hens. So I purchased the new hen and put her in the run with the other hens. Obviously I did something wrong, because 2 of my hens (one more than the other) are so mean to her! They won't let her come out of the coop without pecking and chasing her back into the house. I have food and water inside and outside the coop, so she's getting food and water. At night, they all seem to coexist fine. They all sleep side-by-side on the roost. But come morning, they're at it again, bullying the poor newbie. Are they just showing her who's boss, and will eventually stop?
