yes someone did hatch out a double yolker on here and they had a link to their youtube video. you can go to youtube and search twins hatching and find the video. that video inspired me to try to hatch out a double yolker that was laid on sept. 18th...so far all is good...both yolks have a baby attached to it and when i candle i see both of them moving around very well. i am worried though because there is only one air cell at the big end of the egg.
