I have a hen that laid a soft shelled egg and a hard shelled egg today...I think. I have 4 hens together and only 2 are laying. A black copper and a blue cooper. I know it was the blue that laid because the eggs weren't very dark brown like I've had from these girls. I don't know if it's possible to lay 2 eggs in one day or not. I put out the oyster shell so hopefully I don't get anymore soft shelled eggs. If they start laying soft shells will they continue to do? Thanks!!
