i smell precooked chicken was my first thought ,but latter i disined it to have 2 fans. but i the back wall is all windows on both sections the side wall on the coop side is where the nest boxes cleaning door and chicken door are above the nesting boxes ther ar three windows. then the front wall is all window to the goat door. all 40 of the windowes were free and the hole thing is 16x8 chickens have 10x8 goats have 6x8. it will be alsome better then my coop now it leaks like a sive and i have to clean it every time it rains.
