Dry firing an air gun is harmful and can damage the gun.
I think it will have little to no effect.
Hawks are migrating in many areas right now and are more of a danger.
Confining your birds in a covered run is your best defence.
Hanging pie plates, old cd's, colorful foil streamers, put out some helium baloons with eyes drawn on them. There are lots of things to try, but i was rakeing the yard one day and mama hen and chick were 4 feet from me when a sharp shined hawk swooped by and snatched the chick and all i could do is stand stunned and listen to the chicks frantic crying grow stedily distant as he was carried away.
Maybe free ranging for a couple hours before dark while you are outside watching.
My guineas are my most valuable preditor spotters, sounding the alarm loudly before anything else sees danger.
good luck!
