I have 10 Rhode Island Reds, 2 Guineas, 1 white rock and 2 leg horns. I know the Rhodies are laying already, the white rock started laying about a month ago, very small light colored egg. But last week, we started to get one tiny white egg a day. I'm not sure if it is the Leg Horn, Guinea or the white rocks egg has now turned white. Can anyone help me? Thanks in advanced.
