I've haven't tried it but from what I have never read of anyone being able to successfully move their eggs and set up a new nest for them. Of course considering the alternative is exposing the hen to predators it might be worth trying anyway. There was someone recently who posted about her Khaki Campbell who hid out in the brush and hatched a clutch without getting eaten, it does happen although there are plenty of other times people report loosing their hens. Chickenwire doesn't seem like much protection to me, raccoons for example can tear right through it.

Electroplastic fencing can be a lifesaver when installed around a setting duck that has stationed its nest outside of a protective yard or building.
