Hatching eggs

[carriagedriver]

What happens to those double (or triple1) yolk eggs when the hen decides to incubate them?

 

[ScissorChick]

Same thing that happens to them in an incubator.

Though it's very rare, it is actually possible for both to live.

You will be extremely lucky if you only get one chick out of

a double yolker.
