Double Yorkers and huge eggs?

[DucksOhio]

one of my khakis, 2.5 years old is laying ENORMOUS eggs. The shells are good and hard, I broke one open, content looks fine, but double yolks. Is this in anyway harmful? I can’t imagine passing eggs that size would be comfortable.

As always, thanks!

My Runner ducks did that when they started to lay again after last winter break. They all laid enormous eggs with double and triple (!) yolks and yes, they all were sitting on their nests and were whining in pain during that time. It got better and better with every day and for the rest of the year they laid single yolk, normal sized eggs so far.
