I'm interested in the formex coops you are using. How long have you had them? They look easy to build and clean. Do you like them? Each would cost me about $925 dollars, delivered, are they worth this? I have an old farm. The flood of 2016 blew the middle out of my coop and I have been getting by ever since. I keep about 15-20 birds + 3 young turkeys + what appears to be a banty hen someone chucked in my yard.
