You Can Sex a Chicken Egg?

[lazy gardener]

Just found this thread and looking back i tjink its funny because they have egg sexing now proven to work 100% of the time. There are actually several different ways they do it too. There is air pressure or using air to get a reading of the structures, there is a laser hole technique where they use a microscopic hole to bounce a laser and get a reading of interior stuctures and there is a new way coming out now with just candleing!!

You might find this thread to be an interesting read. By using egg shape, (yeah, I know, it sounds hokey pokey) I've been able to consistently increase my hatch rate from 40 to 60% pullets. Plan to do an other installment on the experiment this spring.

DETERMINING THE SEX OF BABY CHICKS
By Don Schrider
THE EGG...


Many people think that egg shape can be used as a method of learning how to tell the sex of baby chicks. According to this school of thought, pointed or elongated eggs will hatch cockerels and round eggs pullets. I have experimented with this method of how to tell the sex of baby chicks over the years (and there have been scientific studies as well) and the results reveal this method to be nearly useless. Pullets have been hatched from pointed eggs, males from round. If this method had worked, then the poultry industry would have been using this instead of paying for professionals to vent sex day-old chicks.

So how can some people have positive results? Are they lying? Well, in understanding how this method would have any supporters there is the issue of the hen to consider. You see, each hen tends to lay eggs of one shape fairly consistently.

HERE IS WHAT TELLS THE SEX OF CHICKEN EGGS.
Next we need to understand that in avian species sex is not determined by the male, but by the female. The hen has the chromosome which lacks information and by which presence determines sex. Where male humans are XY and female humans XX, roosters are ZZ and hens Z0 (sometimes written ZW). So the male is needed to fertilize the egg, but it is the hen that determines the sex. Also, some hens tend to produce a larger percentage of offspring of one sex, just as in mammals some males tend to produce either more daughters or more sons. Add this all together and you can see that if you have a hen that tends to produce largely daughters and lays round eggs, or produces largely sons and happens to lay pointed eggs, she will “prove” that egg shape determines sex.

Life would be easy for we poultrymen if we could know how to tell the sex of baby chicks by egg shape, but we simply cannot. (For the record, chicken egg colors also have no bearing on the sex of the baby chick inside of it, too.)

@lazy gardener, update?

@Kiki

Yep. It would be nice to get updates from everyone who tried it, not just the ones the theory worked for.

I have a hen sitting on eggs now, maybe I will take a closer look at them.

 

[Akrnaf2]

No.

When people I trust like @yinepu and @lazy gardener post it's possible I think it might be. Too bad neither member posts here anymore.

Each of my chickens, 9 different breeds, individually lay several varieties of thicknesses, shapes, and sizes. Nutrition, stress, time of year, and many other factors can cause variations. Nah. The theory doesn’t hold water.

It isn't worth trying. There is no truth to it. Anecdotal evidence at best.
Same goes for the temperature affecting the sex, it isn't so.
Same goes for the swirling crystal thing. Oh and the one about hanging a chick by its feet.

When people post stuff like that, that is when I quit trusting them.
