I started on my coop construction a couple weeks ago. I had a flu so progress was expectedly slow, but now I am better I find that I am floundering even more. The whole thing has dragged out somewhat, and Ive increasingly felt I may have not designed it in either the most efficient or practical way. Ive used up a load more wood than I thought, its taken lots of time to put together (especially with pausing for thought as ive gone along). I originally wanted the upper half to be lifted off the lower half for easy cleaning. But the sterling board ive used is SO HEAVY!!. It takes two strong people to get the upper half off and is darn awkward. So I will now have to make a large door for easy cleaning instead. The roof was supposed to have a greater overhang on the front, but its so heavy that it makes it unbalanced and I worry about such strong uneven loads on the structure. There are some critical decisions to make now, perhaps why I am dawdling. I need to figure out where to make the door, how big, and weather to make it out of clear polycarbonate to act as a window? I have plywood sheets to attach as the front & rear walls. The door/window/vents will have to be cut into this. But I want to minimise the size as the plywood will give structural strength to the whole thing. The sides will be covered with light timber fence strips as sterling board is neither waterproof or good looking ! I pondered about putting polycarbonate sheet in the upper segments to act as windows and leaving the door without a window. Winter is beginning now, but I also think in summer the door should perhaps be switchable for wire mesh. So there is more air flow. But Im a little confused how to incorporate it all. I dont expect you all to be able to offer much specific help without being able to see everything close up. But if you can spot any major issues, or think of any good ideas to include please share! I have to screw the roof down now, then tar and place felt on it. Im floundering a lot on this, as once its down I cant get it off to readjust! I also only have enough plywood to cut once.
