Chances a sex link could be wrong

I wonder percentage of black sex links fail?

0 percent.
Because genetics...

What about a chromosomal anomaly? I don't know exactly how bird chromosomes work or what's linked to what to make a sex link.
What I do know is that calico coloration, in cats, is usually a sex linked trait. The exception is if you have a male cat that's XXY, which is rare, but can happen. Any animal, as far as I'm aware, can wind up with an extra chromosome and generally function well.
So, can birds have the same thing? Chromosomal anomalies seem to be extremely rare, though I'm not sure if anyone has done DNA testing studies to find out just how rare (in non-human species, at least), but are possible.
So, are there any sex link colorations where an extra chromosome could result in an inaccurate coloration?

Edit: I looked it up, and birds have ZZ/ZW chromosomes, with ZW being the female. So if there's a sex-link coloration where males have a color trait and females don't, then you could end up with a ZZW female that has the male color trait. I don't know if black sex links work that way.

If a sex link seems to be 'wrong', probably that's a species mixup or an improper breeding and not a sex link at all. But I think it's possible, depending on what type of sex link it is, that it could be a bird with a chromosome issue. That kind of thing would be extremely rare, though.

Sounds like a possibility..
This lady won't respond and was arguing with me before hand..
I think she's just blowing smoke..

Then it wasn't a black sex link.

I special ordered through my local feed store from their hatchery. I was *supposed* to get all pullets, sexed at the hatchery: 1 Easter Egger, 1 red sex link, 1 Ideal 236 Leghorn hybrid.

As best as I can tell, what I got was 1 Easter Egger (female), 1 production red or RIR (female), and 1 bantam white cochin (male, bantams are straight run).

So I think the chances are they were given a black bird that wasn't a sex link.

I watched a mini documentary on youtube a while back called The Secret Life of Chickens. They featured a hen that had an issue with one of her ovaries and developed into a "rooster". Maybe this happened to the Facebook OP, too

Hens only have one functional ovary so sometimes when it is damaged or malformed the pullet in question will start to develop some of the male characteristics but generally not full blown rooster traits. You get this watered down cockerely thing for as long as it lives. Also as far as I know that's more to do with a lack of comb/wattle suppression and male-type feather expression whereas in that case we are talking about someone saying a male could have female colors in a sex-link which shouldn't be possible.
Most likely it was not properly bred and therefore is not actually a sex link.

Yeah. Because of the chromosomes of a chicken, a black black sexlink male wouldn't be possible, even with an extra chromosome, since chicken chromosomes are "backwards" from mammalian ones.

She never responded.
After I told her how black sex links are gendered I think she realized the mistake and kept quiet.

 

[Fishkeeper]

Alright, so it doesn't work for black sex links, but what about others? Are there other sex link varieties that could hypothetically be 'wrong' due to a chromosome mixup?

A misplaced chick is much more likely than having a chick with misplaced chromosomes.
