can a double yolked egg hatch?
I would need to see proof and then I would be sceptical,,,,,,I dont know of any such case
Yes, but not very often. The two embryos compete for limited resources (e.g. the air sac) and it's usually fatal for at least one of them.
Its generally accepted that they won't.
But, as usual, no sooner do we say that than someone will come forward and say it is not only possible, but they have done it!
There is a thread here on BYC to that very effect, as we speak. Feel free to search it out.
I have read that a member here was successful, once, and it wasn't recent. I will try to find it. It was mentioned in speckled hens thread about her double yolker.
I do believe it is POSSIBLE - with a lot of TLC and help at hatch time.
I also believe it VERY VERY rare to have both chicks survive and thrive.
PLEASE PLEASE - if anyone attempts to incubate a doulbe yolker, do document with a picture diary as you go!
I was waiting on an egg to hatch for 25 days. I seen movement at day 18 (my candleing skills are not that great). The egg DID NOT hatch. It was a double yolker. If I knew that I wouldn't have set it. Looks like 1 chick was was very developed. But the other did not develope I would guess past day 10. So from my limited personal experience I would say it's very difficult to do.
Speckledhen had a double to make it to day 21.
The resources are very limited so if it ever did happen one or both chicks would probably be sickly, small, or deformed and probably die.
And like Davaroo said Never say Never!!!
