I have 3 red sex-link hens that are 7 months old. I have been getting 2 eggs that are between medium and large size eggs for several months now. But this morning I received a "JUMBO" weighing in at 2.51 oz. That was just huge compared to my girls other eggs. It almost liked like it doubled in size. I don't know which one layed this one but I am so proud of who ever did.
