I've never personally bought one, but as many people have said, they are generally too small. The ones I tend to see at TSC are only big enough for 1-2 birds in my opinion (I'm talking about the ones that say they're for 7-10 birds). I would recommend buying a shed or something larger and doing some modifications to that, if you're not wanting to build the whole thing from scratch.
