Here's my coop that we started on Sat. I am soooo excited!!! I think it is coming along nicely! I put vinyl down on the floor today. We are going to try and finish the walls today. We have used a combination of wood that I have bought and wood that I have gathered from pallets. The roof frame is made completely from wood that I have gathered from a furniture company and pallets. My DH has great ideas for the siding too. He wants to get some pallet wood and stack it like you would the cedar roofing. I'm excited to see what it will all look like when it is finished! Will post some more pics when we get some more finished.
