I realize that this may sound like a very dumb question, but I seriously don't know. I tried doing research on this, and couldn't come up with an answer. Anyway, my question is, does each time a rooster mate (successfully)with a hen, does that only fertilize the next egg that is waiting to be layed? Meaning, does the roo have to mate with the hen everyday, for her to lay a fertilized egg everyday? I guess I'm confused, because with mammals, once the sperm has met the egg, no more eggs are shed until the mammal is no longer pregnant. Well, as we all know, hens are always laying eggs. Now, no poking fun, I've only had chickens for less than a year, and thus far, never hatched out any babies. Thanks for any input!!
