Janus the d'Uccle .... Possible Chimera - male and female???

[animalyodelers]

That's absolutely fascinating. I suppose your immune system 'thinks' you're A positive, because if it thought you were supposed to be O positive it would attack all the A blood cells and you would die.
How often does it change? I feel like a change like that might indicate that blood production happens on one side of the body at a time, or something like that, which I don't think is a known thing yet. Nobody's really tested how much of someone's bone marrow is active at a time, AFAIK.

I thought only negative blood types attack positive types. I am RH negative and have to have special injection while pregnant with 3 of my kids. The 4th was also RH negative so my blood didn't attack him.

I believe that's correct about the blood types, I think only RH negative will attack RH positive. My mom had to get an injection when she was pregnant with me.

I've only ever been typed years apart. I was typed twice as a kid/teenager and was O positive. When I became an adult I was typed A positive a few times. I've never received a transfusion. So I don't know if it actually depends on the day or if it takes years or what. I'm not willing to be stabbed with a needle enough to find out

How did I even miss this?! Im intrigued. In my yrs of being a nurse, I have seen humans that were born intersex. Im excited to see Janus grow.

This is so weird and amazing to me all at the same time. I am so excited to see how Janus continues to grow and develop.

If you have type O blood, your immune system will think that the A markers or B markers on other blood types are infections, and will attack them. That's why people have to have blood of the same type as theirs in transfusions, or can be given O blood, which lacks any of those markers.
This actually came into play when the Black Death was ravaging Europe. The disease mimicked the B markers in blood, so people with AB or B blood wouldn't have an immune response because their body didn't notice anything, people with A blood might fare a little better, and people with O blood almost never got sick because their body noticed the disease early. In areas the Black Death came through, the number of people with type O blood is notably higher, because they were the ones who survived.
Blood types don't really factor in during pregnancy, but RH positive or negative does, and can cause serious problems for all involved. It can kill the fetus, and if I remember right, can seriously harm or kill the mother.

Intersex people can be chimeras, or it can be caused by a hormone issue or cells not differentiating properly. It's actually not known how much of the population is intersex, because it's possible for someone with XY chromosomes to give birth, and for someone with XX chromosomes to have functioning testes. There are also variations where people have too many chromosomes. There's no way of knowing how many intersex people there are without testing everyone's chromosomes. It's all pretty interesting.

Oh how interesting! I'm kind of similar-- I have a thyroid condition and get regular blood tests done, and switch back and forth between A+ and AB+. Maybe I'm a cis-AB?

It's actually possible that you're also a chimera. There's no real way to tell without genetic tests to literally every part of your body, but there's not much else, short of a bone marrow transplant, that causes a blood type change.

Interesting! Sounds like you are probably a chimera too.

That's fascinating. I had no idea. I was recently diagnosed with an autoimmune disorder so I wonder if that has anything to do with it.

But this isn't about me, I am fascinated with this chicken!! Please continue to update

Amazing. Keep us updated! I've seen this in a red sexlink before myself. It was a friends bird. Defiantly an interesting genetic flaw.

And a fact on Ideal and blue mille fluers. The chicks look almost identical to Gooden neck chicke but as they age, if they are blues, the white will slowly start darkening up. Splash, however will not, another thing I've noticed is blue/splash mille fluer will often have black leakage in the feathers. Golden necks are supposed to have been stripped of their "black" and shouldnt have any black cast or feathers in general. So rest assured they could very much still be blue.
I thought ideal sent me Golden necks myself but now they are finally turning blue.

 

[Littleshadow]

Looking at your images, the head of the suspected chimera specifically, I do believe they are blues. Shes got light blue peeking through. I'm uploading a picture of my blue Male, if you look at his tail feathers you can see where he is starting to get his blue. I got my chicks September 6th.
