Which one is laying double yolk eggs?

[jewels4710]

I have 3 RIR and 6 leghorns. Every so often I get a double yolk egg from each. I am wondering how to tell which one of the hens are laying the double yolk eggs. When I start hatching eggs I would like to get the eggs from the ones that do lay the double yolks. If it is passed on. I do not want to hatch a double yolk egg, afraid there may be toubles with the chick. Thank You!

Well if it is a brown egg, it is one of the RIR and if it is one of the white eggs, it is one of the leghorns. Just don't incubate any of the oversized eggs.

Thank You soreland. But that does not really help. I know that I get one from each breed so I have got it down to 9 hens that can be the one laying the double yolk. What I am wondering is if and how I can figure out which two hens are laying the double yolk, One leghorn white egg, and one Rhode Island Red brown egg. I have a total of 12 laying hen.

You should be able to see the double yolkers by candling the eggs before setting them to incubate.
Good practice for when you are candling during incubation.

I had a BO that laid several double yolks the first year that she laid, a few the next year, and then none. I don't think it is a genetic thing as more of a goof thing in the egg laying apparatus. My boys thought is was a bonus to get a double yolker, but I think I read on here that they won't hatch.
