If your male is too busy walking the fences or fighting, he is not paying attention to the female and this can directly affect your egg production. In a large colony breeding pen, there may be several males in a pen. It is best to group males of similar attitudes together, otherwise you have one dominant male fighting the other males and not breeding your hens. If the males are more consistent in temperament, they establish a pecking order and then settle down to do the job at hand. This also allows for more males to stay in season and ready to breed, therefore increasing your chances of fertility.
Females usually come into breeding maturity earlier than males, therefore an older male is ideal.
Depending on the quality of your birds, it is not uncommon for a two year old male to breed. For first year breeders we have found that some but not all of the young males come into season, therefore we often run a large group of young breeders together so that we increase our chances of a male being in season at all times. This situation is a substitution if you don't have enough older roosters to cover young hens. Don't sell them as breeding stock to the next person that comes along and doesn't know any better. Our industry has got to start taking control of our direction, and that means each and every rancher taking responsibility for their actions.
