New Roo; how long before eggs become fertile?

[Carolyn]

Introduced a new roo to a flock of hens and at least 1 is trying to go broody? How long before the eggs will be fertile? He is an adult, courting them in front of me and has the hx of beating out the dominate roo in the flock he came from. They are Rocks and BO's if that matters.

Really fast!

When I introduced my cockerel to the flock, he was about 3-4 months old, so quite young. He also had to establish himself and court the ladies.

I started noticing all the eggs (except one hen that he never did win over) were consistently fertile after about 2 weeks. He was really young, and did have quite the battle to win over the girls though. I think maybe an older roo would be quicker?

I'd start noticing whether or not the eggs are fertile, and when you're seeing it more often than not, give your broody a few to hatch.

Thank you all very much.
