I don't know about discount lumber, but after I framed my chicken coop I built the sides with pressure treated fence boards-- they were by far the cheapest wood at Lowe's and it turned out really pretty.
My Breda are gone

Guess I should be happy, but I do miss them. Sold them at a pretty good loss too, but I'm hoping the guy will keep them as a flock instead of splitting them up. My Exchequer Leghorn rooster started crowing this week and he was way too pretty to eat so I told the guy he could have him as long as he gave him a good home. The Breda girl I have left and my Exchequer Leghorn girl are out there crying, it's breaking my heart. Idk some people say chickens don't understand or have feelings, but they definitely do.
Hope everyone else is enjoying this nice day! It's taking foreverrrrrr to process these quail, I think we're almost done now.
