WHITE LEG & YELLOW LEG = FUNKY EGG?

[Granny Hatchet]

they studied 3 of them. Made mention of that is all they could get their hands on. The pic I put up , there is a thread here associated with that chicken including pics but unfortunately theres no follow up and it was 7 yrs ago.

Chimeras likely happen more often than we notice in chickens and many other species, but because siblings all look so similar in many breeds (seriously, someone help me tell these black sex links apart!), it wouldn't really matter one way or the other if two embryos had merged. We would never know. Moreso still in mixes - you never knew what they were going to look like anyway, so if there's an odd patch of color here or there from merging of embryos, most people wouldn't understand what they were looking at or recognize it as anything unusual. It's easy to chock things up to "well that's what happens when you mix two breeds."

However, with the whole advent of the internet and its love of cats (especially chimera cats!) I have only ever seen a handful of varying-degree-split chimeras (vs just a random assortment of patches or a part of an animal that's mismatched), one of which is Venus, who was mentioned in the articles... and she's not a 50/50 split, of course. Only her face.

And that's out of how many cats on the internet?

Then you have to take into account how cats mate vs how chickens mate - one litter of kittens can have a different father to each kitten (and if we count chimeras, sometimes more than one father to the same kitten!). Each embryo would truly be unique, and still, chimeras are so rare even in a species where genetic mixing is so high.

If she truly was an even split, she would be an astronomical genetic miracle. Two embryos would have to come together enough to form a working organism but stay separate enough to give their respective halves different features. Nature is a wonder...

She's only worth anything in terms of her own value, though. Chimeras don't produce more chimeras, of course - and she may even be infertile or never produce eggs at all. Just my opinion, but I think she's worth more in your hands than anyone else's... you know her story and her genetic history and will tell it better than any other person could! Once separated from the story of her parents/hatching/siblings/genetic history she's just a strange looking chicken, after all

To my understanding - I could be wrong, I'm very new to this - Sebrights are an entire breed that has gender duality, bred into them rather than as an accident of development. The roosters are hen-feathered, and something like having the sickle tail feathers that normally identify a rooster is considered a flaw. They produce female cells to grow their feathers... at least, that's how it was explained to me. It's one of the things I found interesting about them, though it's a bit early to find out which of my four are pullets or cockerels - they're only three weeks old now! Not nearly as remarkable as a Chimera!
