This may be a strange question but I need to know: How long does the actual "act" take? I've seen my roosters jumpin one of my hens but not for very long at a time. Now I don't know what chicken mating is supposed to look like or how long it's supposed to take so I'm not sure if the eggs she's layin are actually fertile. How long does it take? Is there a way to tell if the eggs are fertile without stickin them in the incubator and seein what happens?
