Hello! My DBF and I are working on building our first coop for our four sweet girls. The coop is 3x6, and is elevated 3 feet off the ground so the girls will be able to hang out underneath the coop if they want to. The attached run is 9x6. The exterior walls and roof (which will go over the coop and entire run) will be corrugated metal siding we have leftover from building our house last year. The interior walls and coop floor are OSB. DBF and I are having some trouble agreeing on how we should treat the interior of the coop. My main concerns are moisture and odor control, ease of cleaning, and overall comfort for my girls (of course). I want to paint the interior walls with some glossy exterior "oops" paint from Home Depot, and put linoleum on the floor. DBF is on board as far as the linoleum is concerned, but doesn't think we need to bother painting it. My concern is that the OSB will retain moisture and odor if it's not treated or covered somehow. What do you guys think? I've read through about a million coop threads here on BYC and have seen it done both ways. If a few of you would be so kind as to offer your opinion to this newbie chicken mama, I would greatly appreciate it (and so would my chickens)! THANKS!
