Mine do fine inside an electronet run. I even got some from a farm where they had been free range and they settled down in the run quite quickly. Everything (birds, people, dogs) has to get zapped at least once by the fence and then they learn to avoid it. I even had one poor duckling who got trapped in the fence and was being zapped periodically for I don't know how long before I saw it and freed it. It felt sorry for itself for a day, but now it is fine.
