I'm pretty happy with mine also. I do need a little more protection for the birds in storms. Also, it's sitting on a slight slope and when it rains hard the water will just wash right through the coop. It's wet today. I'm not sure how to avoid that, maybe add dirt on one side to do a mini swale. No such thing as digging a trench. It took a sledge hammer to put in some rebar to anchor it down. I'll have to rent an auger just to make holes for my fencing. Mostly rock. But it is in shade most of the day so it won't get too hot.
To be more specific, just putting a nice thick layer of River rock around and under the coops before I installed the drainage really helped.
