Sure you can. All our eggs are fertile right now. Just pull them each day and put them in the fridge. Stops the growth process. You wouldn't want to let them sit in a nest for a few days and then try to eat them, you would have a partially formed chick.
Assuming they were collected promptly and refrigerated, rather than brooded by a chicken or left sitting out in summertime temperatures, you would have to know exactly what subtle difference to look for in order to even KNOW you were eating a fertile egg!
I was grossed out by the concept, always said I would not have a rooster for that reason, then got a roo and fertile eggs and you know what, it is TOTALLY no deal at all
