I have the same option as choice A. Though I could run electricity I just need a 100' extension cord. Predators like mentioned don't care where your coop is, they find it at some point so just show them up by building a solidly planned out coop/run. Though moisture in my spot is an issue constantly, there are a few things you can do to slightly improve the situation by using gravel and a lot of sand. Covering the run roof (if you have a run) with Clear/UV PVC panels which will keep out the direct rain. Adding a French drain around the perimeter will help in some way with downward trickling water. Shade in the summer, sun in the winter. Good luck with everything!
