You did a great job on the cage itself that is pretty clever, from what I can see. Could you make removeable sheets of plexiglass that you could slide on and off? Not sure if they even make something that big. Just throwing out an idea.I am from India which has a hot and humid climate with seasonal cyclones. We were even affected by the recent Nivar storm with wind speed of 110kmph. The major flaw in my new coop is that rain is pouring from the sides where I used steel nets.
I did the tarp thing too and they got torn, I'm going to put up laserlite (clear corrugated roofing sheets) on 2 sides, so they have light but no wind or rain. Depends on climate though if it will get too hot you can't take it off unless unscrew it. And you need ventilation.There is a drain for the water and there is also a cave like space for 30 hens but the problem is that I fear if they would get wet and become diseased if storm comes. I tried using plastic tarps during last storm but it got torn in half.
