The water bucket is a 5gal w/lid from lowe's that I put a toilet float valve in to keep it full.
The roof is corrigated, smoked pvc panels that I "curved" over a 4" peak.
The 1/2" wire mesh would be overkill. You can see the yellow insulators around the base, these are attached to a Fido-Shock electric fence. My dog, Catahoula Cur, is convinced that the chickens bite. I have come home to find rats hanging, dead, from the wire and have noticed that snakes give the coop a wide birth. We have a lot of Black Racers in the area.
