Rowly, I think that most of what you are suggesting will work. I think you have to rethink food however. They really need access to food constantly. I suggest you get about a 30Lb feeder at the farm supply for when they are past the baby stage. They must always have access to water also. If it is not the pond, then I suggest 5 gallon waterers also available at the farm supply. Think about the nesting cylinders as far as encouraging a laying site.
