I have a hen that I want bred to a certain rooster. She was out with a different rooster for many months. Now I have her penned up with the rooster I want her bred with. Question is what are the chances that the eggs I collect now are fertilized by the current rooster she is mating with? will there be a higher percentage of eggs fertilized by him or will there be a higher percentage of eggs fertilized by the previous rooster? Does anyone know how that works? I know one should wait three weeks to be sure of parentage with the rooster she is penned with but just wondering what my chances are with the egg parentage. Thanks for any info!
