Double Yolked Eggs – Are Double Yolks On The Increase?

I have read that double yolked hen eggs are caused by two eggs separating from the birds ovary at the same time and joining into one egg!

I would like to know if double yolks are on the increase. I rarely get a double yolk duck, hen, guinea fowl or quail egg. Occasionally we have had a double yolked quail egg but I have never had a twin yolked guinea fowl egg.

I am posing the question about whether double yolkers are on the increase as I received an interesting email from Sarah yesterday.

“I have read today in national paper one womans shock at all 6 of her eggs being twin yolks and that the british egg forum states its rare and to find 1 in a box is 1000 – 1 chance. However, I would like to point out that the cheaper eggs that I have been buying from “well known supermarket” are nearly always twin yolks. Easily 6 twin yolks this week in the 10 I have used so far. Im sure if it was looked into this is more common than the experts think. What I would like to know is…how can this be happening so often. What are they doing to the chickens! Is this a case of more interference with nature with inevitably a knock on effect in the human diet? Sarah B”
