    O.K. I've been told that a chicken will continue to lay fertile eggs days and even weeks after the roo is taken away. My question is, "If you place a different roo in next, and he does his thing, will the new eggs being layed have from both roos or what happens here?" sure would like to know... still learning.

    One sperm per egg. Hens can store sperm for at least 2 if not 3 or more weeks.

    Usually, the healthiest sperm win the egg game, so you can often get a mix of both fathers, with likely the freshest sperm having the best chance at fertilizing an egg.

    One egg one sperm. No one egg can normally have two sperm in it and survive. The female donates a half set of chromosomes, the male donates the other half in any sexually reproducing species. Be that an egg from a chicken, goose, dog, human or cat.

    There are cases of polyspermy , but it is rare in animals and is usually fatal to the egg/sperm combo.

    In normal conditions, the first sperm into an egg causes a massive calcium release that keeps all other sperm out of the egg.

    ETA: Here is a pretty informative page on fertilization: http://biology.kenyon.edu/courses/biol114/Chap13/Chapter_13B.html
