Double Yolkers

[Mikeychix]

So I have a genetics question...I have one RSL that lay ONLY double yolkers. She lays one every other day, and I want to know if its just luck or if that breed has it in their genetics, or is known for double yolkers.

I think it is genetic, as I hear some breeds or strains are more prone to it then others. I have a few birds that lay double yolks more often then others, especially one of my Easter Eggers. I get one from her every week or two, sometimes less often (hard to know, as predators have been eating all the eggs).
