I used 2' high 1/2" x1/2" on my tractor run. Not much can get through that. The main fencing is 2"x4" welded fence wire and is more to stop brute force attempts at getting inside.
If the hawk is on the ground and attempting to get through electric fence to get at chickens then it very well may get a zap. One of our girls went to inspect the chicklet run (which has an electric fence) and she took a bit of a nip from the charger. Ruffled her feathers rather well.
