I have one either leghorn or white rock that continues to lay ginormous double yolkers sometimes 3 days in a row! When I say ginormous I mean they weigh 3.3 oz! What's up with that?
There is a gal here in San Diego that has made hatching double yolkers a hobby.... they have to be assisted... because the air sack is not on both ends.

Can u hatch double yolkers?
Very carefully
I've never seen her be sexually active. In fact, now that I think about it, she's 3 and she's never molted, either. Now you guys have me thinking about things that I shouldn't be thinking about. You guys have now convinced me that this bird is a total freak. Maybe she's just a figment of my imagination.

Notin my coop. But my cats did get a mouse today.
