Breeding concerns

[BorneHomestead]

How long after my hens have been with my red rooster will they no longer be fertile with his sperm? They are now with my black rooster and I would like to hatch their eggs with the black rooster being the dad, so how long do I wait for my Red roosters sperm to no longer be in their system??

Hens retain high fertility for two weeks, moderate fertility for three weeks and occasional fertility for up to four weeks after the removal of a rooster. Chances are high that most eggs collected two weeks after removal of the red rooster will have been fertilized by the new rooster.
