Hello! Got some new breeds (to me) this year and they have just started laying. I am getting some very, very large deep brown and very shiney eggs in this bunch and I was just curious which breed was more likely to be laying this type of egg? These eggs are also very thick-shelled. White Rocks Black Stars Dominiques Buff Orpingtons New Hampshire Reds I've had Doms and BOs before, but not the other breeds. Can anyone tell me if any one of these breeds lay a deep brown egg that would be in the extra large category? If I can find this out, I would like to perpetuate her genes!!!
