I just put a rooster with my hens How long does it take for roosters to fertilize eggs?

Roosters can fertilize eggs as soon as they are sexually mature, which usually occurs around 6 months of age. However, fertility rates are highest in roosters that are between 1 and 3 years old.

Sperm from a rooster can live inside a hen for up to 10 days, so even if a hen only mates with a rooster once, she can still lay fertile eggs for up to 10 days after mating.

The fertility rate of eggs also depends on the ratio of roosters to hens. The ideal ratio is one rooster for every 10 to 15 hens. If there are too few roosters, some hens may not be able to mate, and if there are too many roosters, they may compete with each other for access to the hens, which can reduce fertility rates.

If you want to ensure that your hens are laying fertile eggs, it is important to provide them with a good quality diet, plenty of fresh water, and a safe and stress-free environment.
