Couldn’t figure out why Grace, my Delaware, was honking like a goose all morning a couple days ago until I went out to the coop to check for eggs and found this! This egg weighed a whopping 100 grams (approx. 3 and a half ounces), was 3 inches long and so fat that I could not touch my middle finger to my thumb wrapped around the center of the egg!!! In the picture below, the other egg was her egg from the day before and it weighed 58 grams. I was really thinking it was going to be my first triple yolker, but to my surprise it was only a double, her first!
So why does this happen? Double Yolkers appear when ovulation occurs too quickly. Double yolkers may be laid by a pullet whose productive cycle is not yet well synchronized.
In Grace’s case, this was not a fertilized egg, but if it were, it would be unlikely that both yolks would be fertilized. If by some small miracle they were, it would be unlikely they would survive and actually hatch. There simply isn’t enough room in there for 2 embryos to develop fully.
