Okay, I have read a ton of post and the general consensus is 4sq/ft per bird on coop space and 10sq/ft per bird on run space. Even if they free range, it seems people cut down on the coop space to 3 sq/ft and still 10sq/ft of run space (for standards). From what I gather, a lot of members live down south or out west were it seems you have beautiful land for your chickens. (some of the pictures posted make me jealous! ) My question is, what about the urban/suburban backyard chicken owner? With smaller lots, most owners seem to opt for a chicken tractor, but it seems we discount the run space when looking at chicken tractors because I have seen 4-6 chickens in an 8x4 or 6x4 tractor. It seems when we "speak" of tractors, we only count coop space and ignore run space. Or there are situations with smaller coops and runs. Personally, I have a small dog house (5x3) and my chickens ALL sleep in a 1x2 section of it. So, with the suburban coop in mind. If you have 2 hours let say of free ranging daily and the rest of everyday having free access to the run (never being shut in coop except overnight), how much can you cut down on available coop space AND run space from the general consensus. And of course, end up with happy comfortable chickens.... Thanks everyone for your opinions!
