What happens with double yolk eggs?

[Trinitydraco]

So my Isa Browns have had enough time to start laying regularly and my RIR rooster is mating them. (yolks have bullseye) I am planning on setting some with my next batch of eggs but my girls lay double yolks quite often. I don't think a day goes by where I don't get at least 1. So my question is what happens with double yolk eggs when you incubate them? I am pretty sure chickens can't have twins so I am wondering if those eggs can even produce a chick? Anyone had luck incubating double yolk eggs?

It would be almost a miracle if they both hatched. I personally would eat it.

LOL Yeah that's my fear is that not even one would develop due to the other. If a single healthy chick can come out I kind of need to know so that I know how many eggs to set. Of course I can't tell if an egg is double or not until I open it. so if doubles don't hatch at all I will need to put more eggs in the bator to compensate. If they can have a healthy chick then I need to put in less.

Actually I have read on here someplace that there have been successful hatches of double yolk eggs but it's very rare as the egg doesn't have sufficient space for 2 embryos to successfully mature to hatch. I agree, eat them and enjoy all that glorious golden delicious yolk!

Eat them or 5% Chance of hatching.

Can you tell by candling them? I am new to this and don't know how to tell which ones are which as my hens lay both.

I think.

You should get a clue by the size of the egg. An egg laid by a pullet would be considerably larger than her single yolk egg. If your candling device is bright enough, two yolks should be visible unless you're candling extremely dark, blue or green eggs.
I would say it is more like less than 1% of hatching twins and even any live chicks won't be extremely healthy due to having to share space, nutrition and oxygen with a sibling for the first 3 weeks of life.
