Hen ONLY lays double yolk eggs

[TundraFang]

Just to be sure: you have cracked the eggs open and seen two yolks, right?

Because Cornish Cross are rather known for laying big eggs, so if you are judging purely from the size of the egg you might want to check.

Yes, I've cracked them open. They're pretty tasty

Interesting and surprising. The mothers and grandmothers of Cornish X lay hatchable single-yolked eggs so it's not something bred into Cornish X.

The parent-line hens for Cornish X apparently lay a lot of doubles at the start of their laying lives.

This is a little complicated, but our former next-door neighbor worked with a guy whose brother worked for a hatchery. The workers were allowed to bring home the doubles to eat since they're not hatchable in a practical sense. The guy was single so he gave them to his brother to take to work. When they started piling up in the breakroom my neighbor would collect them all, bring them home, and (with our permission), stick them into our outside fridge -- we had a big family and no chickens of our own at the time so we were delighted to have them.

So for 4-6 weeks for a couple springs we had a windfall of these monster eggs.

They were so big that they were transported in every other space of a flat with another flat taped on top with strapping tape. No carton could possibly have held them.

I always cook mine as fried eggs, and my kids alway thought they were a sign of luck.

I had a BO that laid them several times a week for the 1st 6 months, less often after that, and then none the next year.

Mostly I would not worry about it. I would not try and hatch them, the shell while bigger is not big enough for two chicks.

One of my hens has been laying for a few weeks and she only lays double yolk eggs. She's never laid a 'normal' egg since she started laying. I thought it was just because she's a new layer but it's been going on for a while now. Is this normal? Will she start to lay regular eggs as she matures?

Is she an Australorp or a Jersey giant? I had an Australorp who lays nothing but double yokers her entire life. What I'm worried about is I had a jersey who did the exact same thing and the stress actually killed her. Keep us updated on her please!

I actually have a gold sex link that has layed some WEIRD eggs. In the first couple months that she started laying she did like 4 double yokers. She also laced once the tiniest egg with NO yoke! I think she is a special chicken. I still occasionally very rarely now will find another double yoked egg.
