Rural Gardening: Fortress coop ... in some ways, 1 by Photographer

I have constructed this heavy duty chicken shed. It is still a "work-in-progress". The exterior is 90% done. I thought some would appreciate the sight. This thing was made for free using material lying about on the property excepting the 2.5 inch hex head bolts. The construction material is the extra heavy duty galvanized corrugated steel panel exterior fastened onto 1/2 inch OSB or plywood sheets that are attached with nails and screws onto 8 ft tall 4 inch diameter spun posts. These are a common fence post available at Home Depot. There are 8 posts .... 1 post in each corner and 1 more post half way between each corner post. The building is precisely 8 ft square. I cut three of the south side posts 1 foot shorter than the front north face posts and cut the middle posts 1/2 ft shorter. The roof slants to the south at a relatively modest angle. The posts are buried 2-3 ft into the dirt. We have a small chicken opening and an access door I can cover in the winter to keep it warmer. I have 3 photographs to show since 2 sides are identical. The place is not drafty but it is also not comfortably cool in the hot summer yet since it is not yet well insulated. It is more than adequate in the winter spring and fall. Right now the poultry seek out shade since it heats up like an oven in the mid-days to some extent depending on the outside temperatures. There are about 45 -60 days where they really move in and around the building to find shade ... since the chicken run is barren of any shade trees. I leave the water running for the ducks and they're all reasonably happy. They need only protection form predators like mink and not yet raccoon.
