I am not sure if this is the right forum, but what if an egg is fertilized more than one time. I went out to get my eggs and dropped one and it had two places in it that had been fertilized. Is this odd? What would happen if you incubated that egg? Weird stuff!
I don't know if it's possible, but if it did happen, and the egg was incubated, at least one of the embryos wouldn't make it. There's not enough room or yolk in an egg for two chicks.
