I sometimes see a chicken egg with two yolks inside. If the egg were to be fertilized, would the two yolks result in twin baby chicks?

Exactly what the title says! I know commercial chicken eggs are not fertilized (at least not on purpose!) so the yolks could never become chicks. Would double yolks even appear in a fertilized chicken egg?

Chicken farmer here. Even if the egg could produce two chicks it's likely one or both would be born with problems. Just raising normal chicks I've seen that if they are positioned wrong within the egg while developing they have trouble walking and standing and sometimes just can't get off their back if they were positioned wrong during development. This is why we need to rotate the eggs during incubation.
