The sperm sac deposited by the rooster travels up the oviduct within hours after mating. If you have observed a specific hen mating with the rooster then the egg laid the day after and for the following 7 to 10 days should be fertile. Chickens do not need to mate for each fertile egg. After introduction to a new flock of hens, a working rooster should be given 10 days to get everything going. Once the rooster is active among the flock all hens receptive to his advances will be laying fertile eggs.
An egg only lives between 12 and 24 hours. And then it can no longer become pregnant.
It depends on the bird and on the conditions the egg is under.
a woman's eggs are never alive until they are fertilized, womans eggs may be viable but are not alive pre-fertilization. So the egg stays alive until the fetus inside it outgrows it.
They are often still active well past five years.
Depending on conditions a rooster can live to around ten years old but will slow down his mating habits after about five.

Once the egg is fertilized it remains fertilized until the egg is eaten, incubated or goes rotten and decays. It never goes back to being an unfertilized egg.
As long as the egg does not get fertilized it will come.
It is necessary for an egg to be fertilized so the egg can hatch.
A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
Yes, a zygote is a fertilized egg.
12 months duhhh
The gametes, or "sex cells" - the sperm and ovum (egg) - become the fertilized egg (zygote) when they fuse.
A fertilized egg implants into the Uterus.
The sperm doesn't have to. Once the egg is fertilized it stays fertilized.
The average pregnancy length is 40 weeks timed from two weeks before the egg is fertilized.
When a bird's egg is fertilized, a chick is developing inside.
