Are more roosters hatched when hatched by a hen?

[Bullitt]

I saw a video on YouTube in which the person said that more cockerels/roosters are hatched than pullets when a hen hatches eggs naturally when compared to hatching chicks in an incubator.

Is this true?

i have never heard that. i don't know how it could be though. the egg is already fetilized as either male or female before a hen sets or they go into an incubator. i had read that the different sexes of chicks fair better with higher or lower temps in an incibator but i can't find that information any longer. i wonder if this is true can you set your temp in the incbator higher or lower to get more of one sex or the other?? hope you get some good replies.

I've done both hen and incubator hatches and I got more or less the same amount of roosters with both. I've also heard that fat, round eggs are female and pointy eggs are male. That didn't work for me. Though I know people who swear they can sex the eggs like that.
