Our Red Star, Pippin, turned out an enormous double yolker yesterday. She's young, and had only ever given one other egg... a pullet sized one we got from her last week. So... do big double yolkers usually have a thinner shell? This egg was not fragile (all four of us handled it, admired it, passed it around) but when we cracked it, it was a lot thinner than the other eggs we get. I've never had a Red Star before, so I was wondering if it's due to the size of the egg, or if it's typical of the breed. Thanks!
