I just wanted to share this, this was Uno before he died.

A rooster mates a hen, transferring his sperm to her cloaca, she does a sassy shimmy to get the sperm to move up inside the cloaca, then the sperm make their way all the way up the canal to where the yolk has been released, and fertilization takes place up there. Then the albumen or white gets laid down over the fertilized yolk, moves on down to the shell gland eventually and gets wrapped up in a shell. http://www.geauga4h.org/poultry/repro_tract_hen.htm

One mating can produce sperm that will continue to fertilize yolks in a hen for up to two weeks.
 
How long does it take from when rooster mounts chook, till eggs r fertile. The next egg they lay? A few weeks away? Different for each bird?
Probably the egg after next. And all eggs will be fertile for the next week, often for two weeks, and sometimes for up to three weeks (depends on the rooster and the hen).

The egg must get fertilized before the white and the shell are added.
So when they mate, it might already be too late for tomorrow's egg, but the eggs after that should be fertile.
