OK, my son just started a new job....working in a pallet makeing place. As we all know...those pallets are made of....PINE..and he talked to his boss...said I can have ALL the pine shaveings I want, for FREE!!! WOW! I cant believe it! Im taking the truck in there this weekend, for my first load. My son also gets me 2ft x 3 ft panels...sorta like paneling...very thin...pine...and clean. No stains, oils, or grease. I see a new coop in the future...with NICE WALLS! Woohoo! I feel like we just won the lottery...chicken lottery that is!
