We got our 10,(20 wk old) girls from the hatchery Sept 12- within 3 weeks we started getting eggs-We now get 10 eggs a day faithfully. We've gotten several jumbo size eggs that were double yolkers or had really huge yolks. Today we got a HUGE egg, larger even than our largest Jumbo- we named it Torpedo. Due to the size we decided to do a size/weight comparison of the eggs we're getting. The majority of the eggs we get daily fall into the medium/large/Xlarge category. The 3 eggs on the right, the XL Jumbo and Torpedo were all double yolkers. (Somebody out there has a sore hiney I'm thinkin') I sized them according to what felt right from my many years of store bought eggs. This is in no way official- just my own sizing chart I LOVE GETTING EGGS!
