Double Yolk Eggs

[Stargazer]

Do double yolk eggs when fertilised ever product twin chicks?

[PankySmooch]

Yes, identical twins

[Stargazer]

Are you having me on? Is it possible for one egg to hatch into two chicks?

[nailit]

its not the yolk that becomes the chick, its the white (so ive heard)

[nailit]

just done a quick google and it appears that its not the white that becomes a chick either but the yolk is the food source for the growing chick, not the chick itself so no, it wouldnt be twins

Twin Chicks in One Shell?

If the ovums are fertile the double yolked egg will contain two viable chick embryos but there will not be enough space for them to develop to hatching. Unfortunately twins from the same egg are not really possible.

Twins? Yes?

Identical? Not necessarily!

This egg produced 1 male and 1 female. (They needed help to be born because there's not enough space inside the egg for them to peck their way out on their own). Scroll it forward to quickly view the end result:

Lovely video, thanks.

Well they all look the same so I guessed they were identical twins ;o)

Are you being chickenist, Panky?

[PankySmooch]

Yes, sorry Talbot, how fowl of me

I suppose we should have eggspected that.

How cute that video is!

When you crack an egg open and look at it, if there is a small black dot on the yolk, that means that the egg had been fertilised, and the dot is the bit that would have grown into the chick. As previously said, the attached yolk is what it feeds from while growing.

That isn't necessarily the case peachy, it is more likely to be a blood spot.

Peachbabe, I have hens and no cockerel and quite often the eggs have a dark red /black dot attached to the yolk and they can't have been fertilized unless they are playing away with the local wildlife ;-)
