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.

I tested eggs pre incubation using the pendulum method. I attached a large needle to string, held an egg in one hand and the pendulum above it. The needle will start to move on its own. Ive read conflicting statements about which way for which gender but after testing it on all the people and dogs in my house, decided to read side to side for female and front to back for male. I set only the eggs that tested female. During incubation, they always tested the same. They continue to test the same after hatch and two weeks later. At two weeks old I can't say for certain but all 9 of my hatchlings look female to me with how quickly they feathered in. Guess I'll know for sure in a couple months but I'm nearly convinced this is the most accurate way to end up with few to no roosters. Would love to hear if you've tested this. I think most people are too suspicious to even try

First, there is a university study that found that sexing eggs by rounder vs pointier eggs is 79% accurate (vs 50% each of natural lay). That being said, then utilizing the pendulum to confirm makes sense. I have found though, that if you wait several seconds the pendulum swing faster and faster...but that female is circular and male is back and forth. And, to even create more conversation it also works with metal rods for grave dousing. Held parallel out in front of you they cross over top of a grave....and one held at arm's length over the grave spins counterclock wise for women and clockwise for men. I have confirmed this over and over, and the pre-Civil War graveyard beside my house with the newest grave 1866 still follows this method. I use coat hangers, the 15" side and the 6" side for handles (I always use a plastic straw to cover the handles so they swing freely without me touching them). And, just to add a note, I have found the circular motion above an egg with a pendulum circles counterclock wise as well. I don't know how any of this works, but can affirm it does.

Do you have a link to that study?

I read one that claimed to prove that egg shape predicts sex, but didn't really prove anything: they started by knowing what sex chicks came from which eggs, then had a computer use that information to make a model, then found that the model was correct about 3/4 of the time at predicting the sex of the chicks from those same eggs. They did not test the model on any other eggs, just the eggs they used to make the model in the first place.

But you might have found a different study than the one I saw before, and if so I am definitely interested in reading it.
