Budget $500ish ($800 max). I have 4 bantams and want enough to room for 7 max. Here's what I'd ideally like to have but not sure if we'd be able to make it for budget. We should be able to get some scrap wood from the house being built on our street. Or Or I found this on Craigslist for $500 but offered $200 and they' said yes. What's your thoughts?
