Double the Yolk, Double the Fun!

Have you ever cracked open an egg and found not one, but two yolks? Don’t worry, the chicken that laid it is a-okay, she’s likely just fairly young. 

At 25 weeks of age, my flock is still fairly new. When we get our hens at 19 weeks of age, they are just starting to lay, and although our chickens are currently laying mostly small and medium sized eggs, many of the large and extra- large eggs that are laid are double-yolks. The reason this happens is because as a chicken is starting to lay, she still has irregularities in her reproductive system just like any other animal as they move into full maturity. So, a double-yolk egg simply occurs when two yolks rather than one are released in her cycle and then the membrane and shell form around both, giving you an egg with two yolks.

On my farm, we grade and sell some of our eggs to neighbours, and nearby stores and restaurants (the rest go to a large grading station about an hour away), and our customers LOVE double yolks. Not only does it provide more yolky flavour for breakfast and can make for fluffier pancakes, but it’s also a pretty cool way to impress and amaze breakfast guests. In my family we also love double yolks. My mom’s famous cookie recipe requires one double yolk egg and one large egg (please don’t tell her I told!) which makes the cookies a bit more moist and tasty. But unfortunately for my mom’s cookies, as our chickens get a little older and wiser, the amount of double-yolk eggs will begin to decrease as the hen’s reproductive system becomes more regular, but some still will be laid. As a hen ages, her egg size naturally increases as well, meaning that the doubles that are laid later on in her life are typically bigger. These eggs are usually called Jumbo size, which is any egg that is greater than 70 g (for more information on how eggs are sized, check out the DinnerStartsHere YouTube Channel). 

So next time you are in the grocery store and see Jumbo eggs, or crack open an egg and find two yolks, you now know how it got there. And you perhaps now also have my family’s secret to moist baking – sorry mom!
