So we have an ISA brown that began laying over 2 weeks ago. In her first week, she laid a huge egg, that I figured would be a double yolker. We recorded the cracking and it was just that. So yesterday when we see the ISA Brown laid yet another giant egg, I assumed the same. This morning I cracked it into the pan for eggs over easy for the kids and rather then it being a double yolk it was literally just a humongous egg and yolk. Is this just a normal thing for new layers, like a fluke of the process?
