Does egg shape determine gender?

There have been studies in case anyone is interested https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9832119/#:~:text=Sex determination in chicks can be done before or after hatching.

While that is an interesting study they only hatched 47 eggs for the study. It is a good start but an insanely small sample size. You could easily get the same results using a "psychic" with such a small sample size.

I see this is an old thread, but I hatched only four chicks and it is turning out the only elongated egg is a roo!! Now I am fascinated

I tried this experiment with a lot of eggs to choose from. It didn't make any difference.

Here is an interesting article about this theory. Apparently, if measured correctly, there is about an 80% accuracy rate.

Interesting paper but I wouldn't call it conclusive.

"At the end of the incubation period, forty-seven chicks were hatched out of 60 eggs. Eight out of the unhatched eggs were unfertilized and 5 of them were dead-in-shell as determined using candling. All the unhatched eggs were kept out of the evaluation. Chick sexing was done for alive forty-seven chicks."

The study had a very small sample size of 47 and they used chick sexing to determine if they were right. Chick sexing itself is not accurate and opens themselves up to biases.

After the prediction, females classified 80% accurate and males classified 81% accurate. In the study on ducks9, it was found in our study that males have a higher hatching probability than females.

On the prediction side, if our model estimates an egg as a male, it will be 85% accurate, and if it predicts as female, it will be 76% accurate. It means that if our model one egg is male and the other is female, they are not equally trustable. A low shape index value means a very low probability of containing a female chick, but if we have a high shape index egg, it can contain a male egg with a higher chance comparatively.

At the end of the incubation period, forty-seven chicks were hatched out of 60 eggs. Eight out of the unhatched eggs were unfertilized and 5 of them were dead-in-shell as determined using candling. All the unhatched eggs were kept out of the evaluation. Chick sexing was done for alive forty-seven chicks. Female, male, and unhatched eggs are shown in Table 3.

Nothing is 100% conclusive. Its just an interesting experiment with interesting results is all.
