A female will ovulate all eggs on one day of her heat cycle and all of these eggs will be fertilized within 24 hours of each other. Regardless of how many days you breed, the eggs are usually fertilized at the same time. The reason to breed multiple days is that you don't know exactly which day the female ovulates so breeding multiple days gives you a better chance of breeding near the ovulation date.
