No offense but i think she can go for it and i don't "personally think that is a positive thing to say to someone who wants to hatch their own eggs! You are here to give good information and if you don't have facts proving that then stand back and let them do what they choose. Thankyou and pekinlove go for it! you never know what could happen!
Pete, I think you might have misinterpreted what quackers was saying. They just said that they hadn't heard positive feedback about hatching double yolkers and wouldn't personally attempt it because of the high chance that it won't reach hatching. That's a valid statement. I wouldn't personally attempt to hatch a double yolker because if it does fail to thrive it would be later in development and I'd be so heartbroken to lose it. If Pekin does try to hatch it, I'm rooting for that egg. Twins would be SO CUTE. But, I still wouldn't do it myself.
... Pekin, if you do try to hatch it, could you do updated pics candling the egg along the way??
A double yoke egg is difficult to hatch. The incubation process could go well. You may have to step in when hatching begins because there just isn't room for the ducklings to move around and get into position. I would read up of some of the assisted hatching posts just in case you need to step in and help the ducklings at the end.
