Will a Double-Yolk Egg Hatch Two Chicks

[Poultry4Life]

They will either both hatch, one will out compete the other in the egg, or you will have twin chicks.

You never know!! , its like taking chances. but most of the time they never make it.

So do you take them out, now I'm sad!

Despite the risks, hearing above that it IS possible, i wish to try at least once. But i wish to pick the best i can out of my double yolk eggs, to give them the best possible chance at life, no matter how grim that may be. I know a few common sense things right off the bat that might help decrease probability of death, but other things i am uncertain of.

i suspect candling the eggs would be dangerous, as often the air sacks are in strange places and might be easy to rupture while handling. So if i do this, i don't plan on turning one up-side-down. i have an incubator where the egg lies flat, horizontally.

I am wondering....does the SHAPE matter? such as more uniform looking vs more deformed looking?

And is there any science involved with air sacs? Such as Would the number of air sacks matter? is two air sacs better since there are two yolks? is the placement key? one on each opposite end of the egg, where it "should" be, v.s. one in the middle and one is on the end, etc.

i am curious to see if anyone has knowledge of this first-hand. Meaning, you've actually tried a hand at testing what scenarios could make it more likely to hatch when it is a double yolk egg. it doesn't have to be a full blown scientific experiment, but i am looking for someone who's at least done some hands on trial and error when trying to get one to live.

I put in a rather large swedish flower hen egg. I just assumed the mother was 2-3 and layed larger eggs. Hatch day came and one large chick came out and yolk spilled everywhere. One of the yolks wasn't fertilized and never developed. The chick is 6 days old now and towers over everyone.

can you get eggs from the shop will it hatch

Yes, even fertilized eggs that have been refrigerated for a couple of weeks can hatch. But, the opportunity on egg farms for the hen to breed is low. Another but, many stores that sell health foods sell "fertilized eggs," in some way supposed to be better for you, and will hatch if incubated. I have a nephew who wanted to raise chickens. He received an incubator as a gift and being aware of the stories, tried regular Walmart grocery store eggs (cage free chickens may find an opportunity to breed) and out of two dozen incubated he got 6 hatchlings!
