Yes
Farmers used crop rotation to keep the earth fertile.
There were a lot fertile soil in our back yard.
To get non-fertile eggs you need to keep the hen and rooster separated, or get rid of your rooster all together.
Water, light, a fertile soil.
Do you have a Rooster living with Hens? If so, chances are, yes, the eggs will be fertile. If the hen is brooding, meaning she is sitting on top of the egg to keep it warm, then it's probably fertile, if not, then it's not fertile. In any case should you have a rooster and a hen together, and the hen lays an egg, and it doesn't brood, then you should keep the egg warm. I think to check just hold the egg up to a light lol.
Most fertile is the superlative for fertile.
more fertile, most fertile
No. The egg must be fertile, and being in the refrigerator for too long will kill any embryos. Eggs that are sold for consumption are never fertile, unless bought locally. Without a rooster the eggs will not be fertile, and batteries do not keep roosters, as roosters are not necessary for a hen to lay eggs.
The south was the most fertile land in the U.S. and did not have as much luck with manufacturing as did the Northerners. So to keep the same amount of electoral votes the south had to keep up profits to keep population.
When you're fertile depends on your menstrual cycles, unless you use fertility awareness method you can't tell accurately when you are fertile or not. Typically during a 28 day cycle a woman will be fertile days 7-16 of her cycle: ovulation occurs two weeks before menstruation and there may be a viable egg present for up to 48 hours, and for a week beforehand you produce fertile cervical mucus that can keep sperm alive in the vagina for up to a week.
That would be the FERTILE CRESCENT.
