whew. This is the coop so far. The girls are spending their first night in it! I still have the fence to put up and the steps for the door. I had gaps on the side (front) and the door so I used old water hose screwed on to fill in the gaps. There are some gaps where the roof meets the frame. Should I use expandable foam to fill it in? Could it hurt the chicks? The dimensions are 6x4. The girls seems to be liking it. They are all huddled together for the night.
