My best and biggest layer is a large fowl mutt (supposedly from brahma, bresse, BJG and bielefelder crosses) who lays jumbo 75-78 gram eggs. If she ever lays a double yolk it will be huge. With my new pullets now laying, a couple of them are in the running for biggest layers. So far 3 are often popping out a double yolker. I white leghorn laid an 80 gram egg, a sapphire sky laid 75g and an unknown girl laid a long 77g egg today. As compared to my newest layer a BBS Wyandotte who laid a 38g.
Left to right, large fowl mix, sapphire sky, leghorn.
Unknown pullet vs BBS Wyandotte’s first egg.
My diamond duchess laid a triple yolk but I never did get a photo of it. I’ll be sure to post any new jumbos as I’m sure there will be more!
