I hope my question isn't too hard to understand, I'm not exactly sure how to word it. Forgive me if I sound like a ditz but: How much of a roll does volume play in figuing how many square feet you need per chicken? For example - If your coop is tall enough to add a balcony or loft that the birds can get to, does that add to your total square feet? Would a 5 X 5 coop that's only 36" tall equal less usable square feet per bird than a 5 X 5 coop that is 5' tall? Or is the actual footprint of the building the only criteria for determining if you have enough space per bird? Hope this isn't a stupid question but we're working on designing our coop now and I was wondering about how to figure out if the footprint of our coop will be big enough for the hens. Thanks!
