I'm not suggesting exposing eggs to spike proteins. My understanding is that chickens exposed to spike proteins lay eggs with antibodies to them. Exposing chickens to spike proteins is as easy as convincing Congress to raise it's pay. You just jab them. You don't jab the eggs (although it's easy to jab eggs). You don't want the spike proteins in the eggs. You just want the antibodies chickens make that they add to their eggs.
