>The only reason I even know this is that about a year ago I bought a second hand car from the owner of the farm. After we sealed the deal on the car he asked if I wanted a dozen double yolk eggs, I said yes and he gave me two dozen. He had them in his cooler in a seperate area, he had many dozens there so it must not be a terribly unusual event to get one from a chicken.

Perhaps with farms, sheer numbers make this 'event' more often. So As Dragan indicated they have way of knowing
which egg have two yolks and then they put them together. If there was no manual intervention (putting them together)
odds of finding 5-6 consecutive DY eggs run very low.
