I don't believe that would be possible due to the way that fowl store the sperm. Once a hen is bred, depending on the species, she can lay fertile eggs for at least two weeks and in the case of turkeys it has been claimed they can lay fertile eggs for a month after being bred.@CoturnixComplex do you know if there is any resemblance of human and quail sperm? I know in humans male sperm swim faster because they weigh less, but also die off faster. So if someone wanted to increase their chances of having a girl, you would have sex 3 days before ovulation.
So if you took quail, had them mate then incubated eggs (from a certain number of days after mating) you will see more females hatch?
