OK, I'm happy enough with this so far, I know not being there every day isn't the happiest situation, can't be avoided however.
A thought struck me. A secure run for the birds, keep charles, mr. mink, etc. away from them. But, can one be made which is moveable I wonder, more to the point do I have enough level ground for it (Yes, ground is that bumpy/rocky/hilly).
Keeping with that, for days I'm not there, would a floor made out of 1"x1" weldmesh harm the birds feet? I ask as a fox/badger digging under the run would be my main concern, Day's I'm around I'd be happy enough to let them
