Wife wanted laying boxes inside coop instead of the outside of the coop because she said the boxes need to be inside the main coop to stay warm if they are sticking out of the coop they will be cold. I didn't want to go inside the coop each time to collect eggs so I added doors just like a kitchen cupboard and put them in the main coop. Then I added the porch to keep the snow off me. (3 nest boxes just under the window)
