Here is my coop that is made from all free materials except the tarp for 2 bucks and screws left over from home I built last year. There is a place that gives away all left over lumber from building wire spools near me. I'm going to fence around the legs so it can be used as part of the pen and shelter. Not too bad for an afternoon of work. Even put a trap door for the eggs on outside of pen. I turn all my 10 chickens out in the evening. Hope they enjoy their new home. It's a 4x5ft condo. Haha
