I know this may seem like a stupid question, but I am a newbie to the chicken world and so I honestly don't know. I have 21 week old Buff Orpingtons. 4 hens and 1 Rooster. They have started mating vigorously over the past couple of days. The hens have not started laying yet, but my question is when they do start laying, will the eggs be fertilized or is the Rooster too young to be fertile?
