my hens are all just past thier prime at about 15 months, production has dropped off a bit, but the old girls are still laying o.k. this weekend we got the biggest egg we've ever had - a light brown 3.5 oz whopper 6 1/2" around and 3" long. ? we are going to crack it open tonight. i'm guessing double yolker (maybe triple???) is that a big egg or have y'all had plenty of eggs that size?
