Ok. I have been wondering this for a while. Example say if I have a White rock hen, a polish rooster, and a EE rooster. Ok if the Polish rooster mounted the White rock hen. Then a hour later the EE mounted her, Who is likely to have the chick to be theres? And another one say is my EE mounted my White rock, 20 mins later I put her in with the polish and he mates her, How long do I have to wait to know for sure that its the polishes genes in the egg?
If both roosters mated with your hen, either one could fertilize the eggs. A hen can retain the rooster's sperm for several weeks (some say 3 weeks, some say 4) so you would have to keep the hen away from the unwanted "father roo" for about a month before you could be sure his sperm is not used.
Quote:50/50 chance of either being the pa and yep, 3 to 4 wks of isolation before your can put her with one roo and be sure he's the daddy.
