I just get calenders with pictures of roosters and hang in the barn. it works just as well and I don't have to feed themI have a fella who buys eggs from me that insists I need another rooster. I have 14 hens & sell him about 5 dozen a week, but he says if there were more males I'd get more eggs... He's an old timer orifinally from WVA, so I figured he'd know better, but he's serious!
