My husband built this coop using 100% recycled wood that was reclaimed from various old buildings on our property. The only thing we purchased was the chicken wire! It's our "green" coop. I must say I love it's rustic appearance and subtle earthly touches. (We have added on to this coop using more recycled wood. It is now 3 times as big! Plus we are building a 2nd coop! Chicken math, ahhh!)
