My Blue Swedish started laying eggs about Sept. 9. She had around 20 eggs before I took the Drake and put him in another pen area. I started taking away the oldest eggs because she was only sitting on them occasionally. I left her with 11 eggs and marked them on both sides. She has been turning them but still g eggs so those she had after I took the Drake away I took those away from her. Well I candled them tonight, and if I did it right I don't think they are fertile. I did not see anything but a big blob in each egg. Should I see more than just a blob?
