I'm with you on egg size...I only buy jumbo's.
But I have a question....
Let's say some night you forget to lock the hen-house and your prize rooster (Lil Jerry) succeeds in breaking in and nails your favorite two yolk laying hen (Hot Henna)
You know what happened and decide to let Henna incubate the infant and raise it. (right to life)
My question is....does the hatched egg from Henna show two chicks or just one with double the yolk (food)?
I think about this every time I eat a double yolker.
