So, I totally get you. I was lucky enough that I didn't buy a pre-fab for chickens - I got one as a catio. But my cats refused to use it. So, I repurposed it as a nighttime summer coop (they love it). I only have 6 hens, and 4 ducks, and for roosting, it's fine. Not for living in - that would be cruel. I have a tarp over the roof and down one side (the other side borders my back deck so the roof protects it). They can't be winterized in a way that's safe, because even with a tarp, it would get way too cold. I'm not quite Midwest (east TN) but it gets cold enough here that I couldn't use it as a winter coop. Instead, I turned an old shed into their winter coop, complete with heaters. They prefer it to the pre-fab. But I also understand that you can't let yours free range (mine are, but I have a fenced in yard - not that that matters, they still go wherever they want) so you might be better off with a pre-fab RUN, which looks like a huge dog kennel. But then you'll have the problem of winterizing. I suggest you do a lot of reading to figure out what will be best, because whenever an ad says "good for X amount of chickens", they're lying. You'll need a lot more for them to be happy. Whatever review you read that said they have 10 ducks in it, they're either lying because it's a paid review, or they're incredibly cruel. I have 4 ducks and I would never sequester them to such a small space unless it was just a roost.
