Are you sure they aren't meat spots? Unless you had a broody hen sit on them for a few days there is no possible way for a fertilized egg to begin developing.Hi everyone. I found an egg outside (the last three or so days have been warmish but it is December) from Luna, my white leghorn hen. It had something inside! A little blob of pink stuff in the center. I found another egg and it was more developed, with what looked like a little eye (black spot in the center)
