My stepson and I built this coop using pallet wood. We added a metal roof and 2 windows for plenty of light. We have a door that opens to the run with a rope and pulley from the outside. We attached a 4' x 8' run with access to the underneath side of coop. We had a lot of fun building this small 4' x4' coop. We have 2 Rhode Island Reds and 2 Barred Rocks. Can't wait for our 1st eggs.
