No breeds at all that tend to lay double yolkers. That's not actually something that's good for reproductive ability, it's a fluke and not something a responsible breeder would try for, IMO of course. Chicks hatched from double yolk eggs are rare, though not impossible, but definately problematic.
I have a Welsummer who almost always lays double yolked eggs. Every once in awhile she will lay a single yolk egg, but the yolk is still double the normal size. It is really hard on her. Poor thing freaks the other ladies out when she is laying. They all stand at the coop door watching. I think she needs an epidural.
She lays far less than our other Welsummer. Thankfully her eggs are extremely tall as opposed to wide, so she hasn't had any binding issues. I am not so secretly hoping that she prematurely stops laying.
the red sexlinks and production chickens often lay those, they put their all into laying, they seem to conk out sooner than a purebreed in production though
Thanks everyone!
I wouldn't want to try hatching double yokers for sure...I just was curious about which breeds might be prone to laying them. They're just a great surprise to have in the refrigerator when it comes to cooking.
Has anyone had any Buff Orpingtons that layed double yokers?
My gold sex links - or one of them, anyway - laid a few doubles when they first started laying last fall. They were HUGE, I don't know how the hen got them out! I was told it's a glitch in the developing reproductive system and would likely stop as the hens matured. So far, that's been right. The girls are 11 months old, almost, and I haven't had a double yolk since last fall. They started laying young, too - the day after they turned four months old! So I guess they were due for a couple of glitches! I still get some eggs so big I can't close the cartons, but they haven't been doubles.
