Don't feel bad. My first rooster was 10 months old when I got him, the only chicken I ever bought. He had never been with any hens that I know of and was a complete gentleman. My hens I got him for were the same age as he was at the time. It was 5 months before I saw a fertile egg. So, some are just more suave and debonair than others and wait until the lady says "yes".
