If you hatched every egg your chicken laid, you would be overrun with chickens.
Collect eggs daily, and you don't have to worry about any development. There isn't a chick to kill, by eating a fertilised egg. The potential is just there, if incubation occurs. I've left fertilised eggs out on the side for many days before, and there was no development at all when they were cracked.
I thought I had read about ways to stop hens laying, but it was a last resort for hens whose egg laying was so dysfunctional it was going to kill them. Your healthy chicken wants to lay eggs, doesn't seem to have any interest in hatching, so collect eggs daily to discourage other predators from tracking the eggs down.
