Hi all! I am a current owner of 4 chickens, 2 Ameraucanas, and 2 Cuckoo Marans. Only one of our chickens has started laying (a cuckoo maran) but the others are still young so we are not worried. Anyway, we love having chickens and are looking to expand our flock. Our family is debating to either introduce 2 Barred Rocks or 2 Buff Orpingtons. We would like to know which breed is friendlier to people and other chickens, the color of eggs each one lays, how big they get, and which ones are cold hardy. Thanks! PS. This was my first post!
