chick with a pink skinned side and a dark skin side

[crittercaretech]

earlier in the year I had a strange presentation on a chick that was a Ayam Cemani / Naked neck Turken cross. It literally was half of each breed split right down the middle. I have new photos and thought I would share. I would love to hear any ideas of what could be going on with this little cutie. In addition to the skin color shift from left to right side there are a few other oddities. In the older chick photos you can see the color difference in the feet which continues up the leg. The feathers on the front of the neck that make up the bowtie are Black on one side and has about 4 times more feathers than the other side which has 4 light blue/ grey feathers. The iris of the eye on the dark skinned side is dark brown like the Ayam Cemani's have. The light skinned side has a lighter brownish/ green colored iris. The eye color in the last photo doesnt capture the color it actually is very well.

If it is a chimera I wonder if it will be fertile.

Very low chance of that, but the female side seems to be her left side, on hens only the left ovaries develops so if she start laying eggs then she could

Is it just the camera angle or are the feet different looking from each other too?

the legs and feet are different. here is the best photo showing the entire leg is slightly different shade of black

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?

The chick is a Male/Female Chimera. The male of that cross have light/lighter skin than females, Females are id+(Sex linked dermal melanin enhancer) and males is Id(Sex linked Dermal Inhibitor) the Fibromelanosis from Cemani will be partially inhibited by Id but boosted by id+ thats why you see two different colored sides

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.
