I have read that female turkeys only need to be mated with once and they store the sperm and use it as a reserve for making all of the rest of the eggs fertile when they come out. (I have never participated in an artificial insemination project with Turkeys but have seen videos and it appear to be a one time wam-bam thank you ma'am type deal.) I have had several turkeys and they usually lay 1 egg every other day or every 3 days sometime, laying span usually lasts about a month, average harvest from each female is about 15 eggs. I have also seen that the male generally only mates with each female once during this process. The question I have is: Is this the same for hens? I am inclined to think that it is not so dramatic, the storing of rooster sperm for a month that is. I also have several hens and roosters and usually the activity in the run is a lot higher. I am lead to believe, based on some seperating experiments that i have done (hatching in incubator) with a few pairs of chicken, that their sperm storing period is only a few days. Where I live, i participate in a farmer's market kind of deal on Saturday and Sunday, I take chicks, fertile eggs and I like to take a few of my best roosters to demonstrate adulthood for the chicks. Only seperating the male from the females for 2 days, really only being 1.5, i have seen no drop in fertility. I am looking to see if anyone can give me an exact answer as to how long a hen can keep pumping out fertile eggs without the presence of the rooster (after seperating them). Maybe all hens and roosters are not the same but a good explanation to this inquiry would be personally aprecciated as well as fun to share with some of my students. Input?, thanks.
