My gold sex links started laying on 8-25-09. I have 4 laying now and they have laid a variety of sized eggs all different shades of brown. So far I have 14 eggs (one was a soft shell) three of them were jumbo, two were a regular large size and the rest small. This egg was laid on Monday by one of the girls (not sure which one). The egg has this ridge all the way around it. Do you have any idea why? I just want to make sure there isn't a problem. Also what is that white stuff on the shell? It does wash off so it isn't part of the shell color. Thanks in advance for your help!
