A weird question about a strange chicken

[fancyfowl4ever]

chimerism is a cool thing indeed. I have seen a couple pigeons and doves with it, not too many chickens tho.

Basically what happend to create them is that the egg got accidentally fertilized by 2 sperm instead of one and merge together in the growing stage making 1 being with 2 different sets of DNA. In birds it seems to always split them down the middle, one side one bird the other another.
It happens in humans(people with 2 different colour eyes for example), but in humans it is not as noticeble or clear as it is in birds. Not so clearly displayed. In humans its very spotty, some may just have an off coloured tuft of hair, others may have patches of skin that doesn't match the tone of the rest, eyes different colour and sometimes you cannot tell visually at all. Sometimes the outside is one DNA profile while the internal workings are another.

I've never seen that before in chickens. Kind of neat.

'Chimera' animals occur when two embryos fuse and become one animal in very early development. Male calico cats are the prime example of naturally occuring chimera. The very rare male calico/tortoiseshell cat is often a chimera of a black and an orange embryo rather than the phenomenon called 'mosaic' (groups of two different color-producing cells in patches) that produces female cats of this color. Since the tortie/calico mosaic pattern is sex-linked, requiring two x chromosomes to manifest, the only other option for getting a calico male is what is called Klinefelter's syndrome--a male that is XXY instead of XY, and usually sterile because of the genetic fault, while the chimera cat will be able to reproduce.

Sheep/goat chimeras have also been produced in labs--they look like a Frankenstein's monster made of a mix of sheep and goat parts, rather than a crossbreed between the two animals. Very strange.

GOODNESS.

Unbelievable stuff here tonight.

How did I miss this last week?

OK, NOW, you can poke my eyes out, I've seen it all.

My cousin has 2 different colored eyes...

That is a very cool roo! It's a shame you don't have pics of the chicken you had when you were younger...

I guess pigs really do fly

Pretty neat looking birds though!!!

Yes I once quoted the same thing about seeing it all myself.

I used to work in a tire shop, and when I say Ive fixed a few tires in my life, I mean thousands, and I thought I had seen everything that could flatten a tire , till I once pulled out a snake fang then I said that I 'd seen it all. Well, this thread proves that I stlill havent seen it all yet, so Mahonri you just might want to keep those eyes a littlle longer still yet.
