The old "need a roo to get the hens to lay" argument, eh? Eggs come from the girl/hen regardless of the presence of a male/roo. Do human women stop ovulating if they are single? I think not. All a rooster is going to do is fertilize the eggs to make baby chicks. I can't tell you how many people do not get this fact. Recently on Regis and Kelli, Regis was interviewing William H. Macy and was unable to understand this fact, not believing what the actor told him. Eggs are produced to be fertilized, but most are not. The hens continue to lay as their biological clock tells them to do.
