So I'm starting the plans for a "coop" for a couple of pairs of wild ducks (Biakal Teal ,Smew etc) along with a couple of pheasants and doves. In my ponderings I came up with a Drywall Coop. Its cheap ,fairly strong ,and easy to screw together. I can make a 4 x 8 "coop" for roughly 80 dollars ,give or take. However ,I would want to seal the dry wall again our crappy Canadian weather on the outside and the mess of the birds on the inside. So ,I was thinking ,seal the whole thing up with liquid rubber. Once dry ,its waterproof and for the most part to tough for the birds to chew up (although I doubt that pheasants and ducks would have much interest in chewing on walls...their not stupid birds like chickens ) So pretty much make a drywall coop ,cut the out holes for a pop door ,window ,and vents ,and then slice out most of a wall to make a door into the coop. Seal up the entire coop except for the top (that'l be shingled most likely) with the liquid rubber ,and seal up the door at the same time (at this point not attached to the coop). Once everything is dried ,screw hinges into the door and coop ,attach door ,and boom ,weather proofed easy peasy super cheap coop. Any ideas or incite into my ponderings ?? Either way I'll be starting this quite soon.
