Something to illustrate my point from the Florida Fish and Wildlife Commission........
Hen harvest to reduce population levels is unnecessary and can be detrimental to the population as a whole. While areas with good turkey populations can withstand limited amounts of hen harvest without impacting the population, the number of turkeys available for harvest is closely linked to that year’s reproduction. During years with good reproduction, a higher number of turkeys can be harvested with no adverse impacts on the population. However, during years with poor reproduction, there are fewer young available to be harvested and hen harvest would consist of adult birds, which could adversely impact the population since adult hens are more successful in raising offspring. Moreover, to successfully implement hen harvest would require annual turkey population surveys, which are difficult to conduct adequately, are labor intensive, and costly, making such a program unfeasible, at least on a large scale. Further, since turkeys are not known to over-populate and do not damage their habitat, there is no biological justification for pursuing hen harvest to alleviate such perceived problems. Generally, individuals with areas supporting large turkey populations are fortunate and should not be overly concerned with an abundant population.
