We purchased a farm with a small horse barn. In the back is a small building which was used by the first owner for raising chickens. The coop is an unsightly mess, looks like it has never been cleaned. What is the best way to clean an old coop and how? What products do I need to spruce it up. Has anyone tackled a project like this? I was planning to turn it into a potting shed Thanks so much for any suggestions. Thanks for letting me be a guest on your site!
