One of my Production Reds laid a huge egg. Some of them have been laying for over a month, but all of the reds have been laying for about two weeks. I just want to make sure something isn't wrong. It had two large yolks. The shell was paper thin, it cracked while I was washing it. And the shell was also rough, and had ripples in it, no smooth sheen to it at all. It is pictured with large to extra-large eggs. Should I worry? Thanks!
