    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!

    There is no way of knowing for certain. I'd just wait the three weeks.

    Good luck.

    Quote:X 2 After two weeks the chances of fertilization by the desired rooster starts to increase. By three weeks it is a very high %, and by 4 weeks it is guaranteed.

    I read somewhere that after a hen mates with a roo, she stays fertile for 5 days. So I would wait at least a week of putting her with the new roo, and then start gathering the eggs for hatching.
