I have an old hog shed on my property and was thinking of making it into another coop, since my main coop/run is at capacity and I would like to hatch some offspring from my current flock. The hog shed is bigger than the main coop but needs some work. Any experienced coop builders have some ideas for me? I know the floor needs to be filled in, and some of the gaps in the tin siding patched, add a roost and a door, and some screening over the vent on the top of the wall. Anything else I am missing? My main coop is 6x9 with 10 birds, this hog shed is about 8x12. I also have too many roosters, so until I decide what to do with them, they would be in the hog shed.
