So I'm the new owner of 4.14 acres, and the first thing we want to do is get chickens. I have a huge fenced area for them during the day, but no coop yet. We're thinking about 12-15 hens. I'm thinking I want something about 8x6 or 8x8, and am pretty good at framing with dimensional lumber. I've been thinking that it will be raised off the ground about 6-8 inches, will have a 3/4" plywood floor (probably covered w/ some sort of cheap vinyl remnant), and will be framed with 2x4s. I was just thinking today though, that I could save a lot of money if ripped the 2x4s in half. Would a 2x2 be too wimpy? Also, what about siding? The cheapest thing I can think of is 1/2" CDX plywood. Is there something cheaper (besides what I can scavenge for free)? For the shed roof, I was thinking about 1/2" plywood covered with some fiberglass corrugated panels. Is that a good/bad option? I'm really trying to do this on the cheap, and my calculations already have me in the $700 range. I'm hoping to get that closer to $400 or $500. Any suggestions?
