Sexing eggs!

[Guyswithchicks]

Hello everyone, well the results are in....for the time being anyway.
So I had 22 chicks hatch from randomly selected eggs. The result, 11 male and 11 female.
This is what I would normally see over a season. I have chosen hatching eggs for size, shape and general quality.
Now for the selected, rounded, less pointed experiment.
In the first round 18 chicks reached sexing age with a disappointing 12 male and 6 female. The eggs I selected can be seen in my previous posts.
In the next round I incubated the eggs and this resulted in 26 chicks. 12 male and 14 female.
So in total from the selected eggs I got 24 male and 20 female.
Once again, close to the margin of 50%that i am used to.

Aww that's so disappointing!

That is disappointing

Your random eggs, were they from one or several hens? From what I read comparisons (round vs pointy) should be eggs per hen. Wish I could get a rooster, I want to PLAY!

The eggs are from several different hens as I have h flock of around 100 layers.
I haven't given up quite yet and will get a bit more scientific a bit later on.
Yes I was a little bit disappointed but in the last batch where I had more females than males, the eggs were slightly less in volume.

I recently did the oval egg shape experiment with seven eggs. I ended up with four roos and three pullets. I don't think the oval egg shape is reliable to produce all pullets.

Thanks for posting your data. This is what we're looking for! Multiple trials, with as much information as you can provide. I hope to put up a survey sometime next month. If you wouldn't mind keeping your info, and posting it in the survey, that would be great!

You are correct in this statement! IMO. We're looking for a trend. It might also be interesting to look at gender based on season of hatch. Do warmer weather temps favor one gender over the other in terms of hatch rate?

Just put 30 cream legbar eggs in the incubator. Have put them all in but will split them up to hatch so that I can see what percentage of the round ones are pullets compared to the percentage of the whole group.

This is just for fun.

I am on my third incubation this spring. I have had a time of it as this is the first year that I am hatching with an incubator. My first hatch gave me only 1 out of 17 eggs. That was a tough pill to swallow as it hit my arrogance hard; I believed that if a chicken could do it then it must be easy. Now I have had to face the sobering thought that a chicken is better at something than I am!

But, the last hatch was 3 out of four ducklings, 3 out of four bantams and 1 out of 1 buff sussex! Yippeee

They are now two weeks old and, this is the important bit, I set all non-pointy eggs. They should be, according to science, pullets.

I have no idea what they are yet gender-wise but I will announce it on here. If anyone else also wants to set non-pointy eggs and tell me what they got, I would love to hear about it.

The key is not the roundness or length of the egg but the least difference in the circumference at each end of the egg. see photo diagram.


Sorry its sideways but basically, in the picture egg A would be a roo and the others pullets.


Who is with me in this egg-speriment?

If you do it again, please share, this is very interesting to me.
I didn't think there was any way to "sex" eggs and didn't think the shape of the eggs meant anything. Curious if anyone else has ever tested this theory!

Yes. My pullet rate in 3 hatches consistently improved from 40% (prior to shape selection) to 60% with shape selection.
