    I don't know much about breeding birds in general, and know even less about chickens.

    If a hen lays an egg every day, and shares a household with a rooster, will her eggs always be fertile?

    Scenario .... if you have Rooster A and he mates Hen B, how many eggs will she lay before she finally lays the egg that Rooster A fathered?

    Just wondering how that works, especially since hens lay eggs even without a rooster.

    Most folks say it takes a week to 10 days with a roo before you can be certain that the eggs that come out are fertile.

    A rooster mates with the hens and she is likely fertile within the week, storing the sperm, for up to 3 weeks. However, most roosters see that their harem is mated much more frequently and often has his "favorites". An active, virile rooster can keep about a dozen hens in fertility. Not all hens are as good at being receptive and not all roosters are as proficient in accuracy as others, but you get the idea.

    It is quite likely that they will be fertile unless for some reason a hen isn't getting bred (not being a favorite as mentioned). You can tell if you look for the bullseye in the egg whether they are fertile or not. Post # 6 has a fantastically clear photo of what a fertile egg looks like. In an unfertile egg, the germinal disk just looks like a white speck.
