I plan to get 2-4 hens next spring and I am planning my coop. I live in Louisiana and I am more concerned with heat than with cold. Our temperature dips below freezing about 40 nights a year, but it only dips into the 20s a few nights a year. We rarely have snow. On the other hand, our temperature often breaks 100. I am thinking about a 4x4x4 coop with a gable roof. The peak of the roof would be about 1 foot from the top of the walls (could be higher if that would help). I plan to have vents in the doors and a large window, all of which can be closed in the winter. I am thinking about leaving the gables open permanently except for hardware cloth. The roost will be 25-30 inches from the floor or about 18-23 inches from the bottom of the vents (I want the roost high enough so that there is enough head room under the poop board). Will the 2 open gables be too drafty in the winter? Should I reduce the size of the openings, or close one off completely during cold nights? Should I design some sort of baffle to keep the wind from blowing in one gable and out the other? Any suggestions will be greatly appreciated. I have not built anything yet, so I am not married to the design.
