How long do I wait?

[chick lovers]

I have recently acquired an EE rooster, and separated I'm and seven EE hens. The hens have been mounted by several other roosters and I was needing to know how long I need to wait until the eggs are straight EE rather than having PR or BO mixed in
them?
Thx.
Dan.

Hens can retain sperm with high fertility for two weeks, moderate fertility for three weeks and occasional fertility for up to four weeks after the removal of a rooster -3 weeks if you want to be 90+% sure that the new rooster is the sire of the chicks.
