chick with a pink skinned side and a dark skin side

[Painted Calls]

This is the coolest looking bird, ever!

Right!

yes the color change does down the neck but is less noticeable on the body.

Oh, that last pic shows it better than that side of head in first pics.
How fascinating.
There's a name for this....chimera?

Yep!

 

[RoyalChick]

Yep!

I believe it is a chimera. Happens in all animals - often from the fusion of non-identical twins at a very early stage of development.
Some cool examples here.

Seriously cool.

That’s the coolest thing I have ever seen!

How old is this bird now?

 

[RosemaryDuck]

Will you be breeding this one? This would be such a cool project. Either way, it's a stunning bird!
