Probly two days and you should have fertile eggs if they are laying regularly. This time of the year your probly doing really good if you get an egg every other day from a standard bred hen.(in natural lighting that is)

On the clearing out of the others older semen to the newer cocks, there's lots of variables here I'd say from 2 weeks to 4 some rare instances proves the latter false also, not a set rule just an approximation is the best you could hope for here.

My chickens lay more this time of year than in the summer here. Yesterday because some are just starting to lay and some are just getting over a molt, I got a record 18 eggs from the hens. Granted I have around 30 hens. My Leghorns and Heritage Dellies lay everyday. All year. Brahmas and Reds lay around every other day. I use no light in the hen houses. Mine are outside all day everyday. I really see no drop in the winter compared to summer.
Reason I also asked the question is I'm doing a test with my Leghorns. Candled today. Out of 30 eggs had to throw out 2 for blood rings. All the rest have the good spider veins going on. Left the cockerel in there for a week like Ron said before collecting eggs. Have him in there with 4 hens. So, so far after a week it's looking good.
