So I have one hen that lives separate from the flock, because others bullies her.
And if I want have chick's from her how long after I put rooster with her and see them mateing will she lay fertile eggs, and how long will she lay fertile egss. She is my best egg layer so I want continue that line.

Once the hen in mated, she can remain fertile up to 3 weeks. Good luck!
