so I have 6 8 week old chickens currently living in my basement. im hoping to get my coop finished my the end of the month. but im still trying to figure out how to do the roof and doors. and im wondering if I should Thompson seal the whole coop being that it's made from osb. I got my roosts built. im thinking no more towards a lean to roof. i also need to figure out how to connect the 3 boxes.
