I'm on high ground 45 miles north of Fort Walton Beach FL now but used to live in Destin. We had some flooding with some tropical storms. The longest storm I had to deal with was George. Three days of wind and rain sitting on top of us. And the surge. That was something. Opal ripped through quick and pushed everything, sand, boats, barges, homes, up to high ground. I have a tightly screwed in long roof on my main chicken house. The feed shed is connected to that. Yes, it still leaks a little if there is a hard rain. We learned that if we seal our metal trash cans seams with silicone caulk, inside and out, and line each new batch of feed with a heavy duty can liner our feed stays dry and bug free. Each can holds 3 50lb bags of feed. I learned that the price of feed goes up when gas goes up after coastal storms. Our property is the highest point of our neighborhood. No more storm surge for me. Our coops are almost storm proof. If one of our trees goes they will take out whatever is underneath. So, its up to you. If you have a high and dry spot to store feed and put your birds do it. Good luck
