We are building a coop from scratch. The floor is cement, and the main part is brick with one door (for us) one small door for the chickens, two windows that open and one small vent near the top of the coop. It's not to large, less than 6x6 feet. We want to do this right the first time so we don't have any redo's down the road. We will have about 12 hens, do 4 nest boxes sound like enough? Just looking for opinions on those who have done it before and what they wish they would have done differently BTW, we will also have a large totally secure run but that part won't be done till spring most likely.
