Siamese chicken?!!

So, I am hatching eggs and one didn’t hatch so I did an eggtopsy. There were two chicks conjoined at the chest.

The egg stuck so I disposed of it without taking pictures!!

What!? Wowsers that's gotta be rare!
Did they share the one yoke or was there 2 yokes?

One yolk

That's crazy!

One yolk

That's even rarer!
From what I know with human Siamese twins, it happens when the embryo goes to divide into twins but never divides fully. I was told the only way to get chick twins if from a double yoke egg!
