You know, I've got a hen that lays me huge eggs now and then (I call them "wombos"). The largest was 4.10 ounces, and I thought for SURE it would be a triple, but nope! Kinda disappointing.
Oh, and double yolkers do not hatch. I read online where someone supposedly successfully hatched 2 out of a double yolker, but typically they are unhatchable. There's thread on here where Speckledhen tried to hatch a double...if anyone could do it, SHE certainly could with all her experience; it did not work.
