this is my first chicken coop. I have 7 chickens, 3 white, 3 brown and 1 little black hen. They all lay brown eggs....I'm not really sure of the breeds. I have an 8x10 shed that my son in law built for me and we put a dog run on it for the chickens to go out in. We put field stone around the entire bottom of the coop and run so that nothing could dig under the fence and get them. I have 8 laying boxes in the coop that they lay their eggs in.
