My first coop, at one time was a reptile cage made of wood. I no longer needed a 8ft x 3ft cage and couldn't fit it in my newly bought house's doors. So I decided to turn it into a coop. I took the glass out and replaced it with wire. But unfortunately it was not made to withstand outdoor life. So the doors fell off eventually and rotted. I'm having to replace them now. So if I was to do it over again I would of sealed it and painted over that with some outdoor paint.
