Question on fertile/not fertile eggs

[augiedranch]

If I want to let my hens out to free range with the rest of the flock, and the flock has other rooster's. After penning her back up with the rooster I want her bred to, when would I expect those eggs to be fertilized by the rooster penned with her. ..? Thanks in advance!

Hens can retain high fertility for up to 2 weeks after being bred, moderate fertility for up to 3 weeks and some fertility up to 4 weeks after being bred. After 3 weeks the chances are high that the eggs will be fertilized by the desired rooster.
