Hello! This is my first post to backyard chickens! I'm also a first time chicken owner. We purchased chicks at two separate times from the same hatchery - is it ok to put them together without worry of disease? I currently have them separate because that is what is advised (plus our other birds are 2 weeks old and almost triple the size and the new little ones). But they did come from the same hatchery so logically, they would have the same "germs"? The hatches are 2 weeks apart. thanks for any feedback!
