Pendulum sexing experiment.

[The Moonshiner]

Since this method isn't harming the chicks (* some methods do)

Which methods are those?

Common myth is you can determine the sex of a chick by holding it upside down.
But nobody can agree on which reaction means pullet, and which means cockerel.

Usually freezes and pulls legs up to body = female
Usually doesn't hold still and kicks legs or extends them = male
I thought you meant seeing eggs since that's what OP was doing.
Angry wing sexing is the most accurate for young chicks.

Ah, yes I didn't correctly explain myself.
I meant that there are myths people use on living animals to determine male from female, that can cause the animal harm.
I don't see any issues with using egg myths? since the egg can't panic and suffocate like a living bird can.

I always forget about the wing/feather sexing thing until it comes up and somebody has to say "only certain breeds are selectively bred for that. Yours isn't"

I was talking about a different kind of wing sexing.
But ya with the wing sexing you're referring to I see the same quick replies about the breed needing to be bred for it.
That's actually not correct or it'd be beyond rare.
Wing sexing works because there's a sex linked gene for fast feathering and slow feathering. Like other sex linked genes females only have one or the other and males can have 2 of either or 1 of each.
To work it needs to be a fast feathering male over a slow feathering female. That cross gives females a fast feathering gene and males get one fast and one slow. Slow is dominant to fast so males feather slow and females fast.
That's the basics so it's done by crossing a fast feathering breed rooster to a slow feathering female.
For a breed to be bred for it you'd need one breed but two lines. One fast feathering and one slowing feathering. I've nevered heard of a breed that comes in both or anyone creating both with a single breed.
Hope that makes since so next time someone tells you you have the wrong breed you can tell them no I have the wrong cross of 2 breeds.

I haven't looked into the feathering stuff. Didn't pay attention to the phrasing people used
It seems like it's usually someone with just whatever bird (eggers are popular, for example) and it's like "there's no way to know since we don't know what was used to make that bird there"
Might have been more of "not every chick can be wing/feather sexed"

But if it's a sex-link crossing, then most purebreeds wouldn't qualify either way, right?

The same purebreed breed as rooster and hen no. Two different purebreed breeds yes. Leghorns are fast feathering so a leghorn rooster over lots of other breeds work.
