Egg fertility time

[bigz1983]

I gave away a Blue Amerucana rooster about 2 months ago and just got a Jubilee Orpington rooster on April 24th almost 2 weeks ago.
He is in a coop with 11 hens.
Do any of you guys have any idea how long it will take for all the eggs out of the coop to be fertile from the new Jubilee Orpington rooster?
Are they most likely fertile by now?

They are most likely fertile from the new rooster now. A general rule of thumb is high fertility for 2 weeks, moderate fertility for 3 weeks and slight fertility for 4 weeks after a rooster has been removed from a flock. After two months it is unlikely that the hens retain sperm from the first rooster.
