Most of our flock have quit laying, the ones that still do are the sexlinks and a brahma hen that our Dominique could got our brahma hen but I didn't think rooster semen could fertilized an egg of hers in less of a week. She's only blended in recently and if it was the Dominique he got her maybe 3-5 days maximum before I put the eggs in the incubator. I thought it took about a week for the fertilization process to occur with chicken eggs from conception to the point where the fertilized egg was laid. The other rooster in that flock is a brahma. The Easter Eggers and SLW rooster are in a different coop. If I'm too understand correctly, barred overtakes partridge pattern so I'd end up with barred chicks but no white head spot that would indicate a sexlink, correct??
