With a lot of coops out there there are different companys making the same coops or slightly different versions of a certain design.
If you happen to be from missouri I know the company that makes them. I also know there was a guy that made at least a couple that were almost exactly the same that is no longer building coops.
Ive also made two of that design but mine were different colors. If you are from missouri pm me and i'll give you the company that I know of name. If your from else where let me know what info your looking for im sure I can help you with it.
