You are doubly blessed, for the time being. I have a Blue Sapphire who is now 2 y.o. that was doing just that in her first months of laying, she's now only laying regular eggs. Your girl's excited system should settle down.
Changing diet ( less protein) and light exposure ( in darkened room) does work for hens. I've had to do this to treat a hen so her prolapse and vent gleet could heal.
