I'm sorry, I'm just trying to help. I recommend going out and buying a large dog crate or two. Since your coop is large you should have no problem fitting it in there. I think it's a good investment as it's always good to have a place where you can separate bullies, sick birds, and new chicks.MY COOP IS VERY LARGE AND TALL I HAVE NOTHING THAT COULD KEEP THEM SEPERATE
