Our chickens started laying a few weeks ago. My mom sent the second dozen home with me. My kids and I were making omlets with them and found a double yolker. I had to call my dad and let him know. Then this last week end we had a picnic at my parents my dad was telling me that when the were slicing the boiled eggs for the potato salad they found another one with 2 yolks still pullet egg size. I told my dad we must have a hen that is laying double yolkers. What do you guys think???
