Welcome to BYC.
When figuring your coop square footage, it should not include nests. The roosts in prefab are almost always too close to the walls and each other. The ventilation is not adequate. (You need 1 sq foot per chicken always -open and above their heads ventilation space, especially in the winter.)
Your run needs 10 plus square foot of chicken and additional room for the feeder and waterer.
If you must use that coop, stick with smaller breeds.
