My girls have been laying for about 2 months now. I keep getting one of the eggs a day that is spotted. At first I thought it was just the egg colour; then I had to scrub some stuck on,,, well you know.... and the spots came off. Should I be concerned for my girls? You can kinda see it the best in the one just above the Jumbo Egg. She did not lay the jumbo, I know that for sure.
