The wood was coated with a porous coating. It's very humid in east Texas, so I sprayed the white pieces with a white polyurethane, and the roof with clear urethane.
Also, there is no latch on the hinged roof of the brooding box, so I will just install one.  Raccoons would just open the door and walk right in if nothing is holding it closed. No biggie.
This coop can only accommodate 2 larger chickens like Ameracaunas. It could possibly suit 4 Bantams.
