Aww, good for you for experimenting with them in their new little enclosure, I have my fingers crossed for you, it should be all good, I don't know if a hawk would want to get in that close, with the trees right above the run like that.

The reason we've been so lucky with predators is a bit of a catch 22. It's because we live right on the highway, and there is a factory across the road from us that runs all night, it's got huge fans that turn on periodically and is always lit up too, so I think predators don't find our little stretch very appealing as they can't be very sneaky and they are afraid of the lights, cars and noises.
