If I get Hatchery chicks it's going to be ee's. I don't really know anything about Hatchery birds so I don't even know what questions I'd ask. Ee's are supposed to be pretty sweet tho. I'm glad you brought up the mareks point because I hadn't thought of that a day I think you changed my mind about that. I don't want to pose any risk to my birds at all. I love them!
