I was all excited to receive my new egg scale. So I weighed a few of my eggs.....pee-wee to medium... My hens are now 27 weeks old. When should I start getting some larger eggs. I know the Dominiques will lay a smaller egg as they are a smaller bird. I also have black jersey giants, black astralorps, buff orpingtons, speckled sussex, americanas,partridge rocks, and one white cochin. The quality of my eggs is awesome! The size, It seems the size fluctuates, some days they are larger than other days. Oh and this egg scale is really awesome! $33 shipped!
