Even though the female lays only two eggs per nest attempt, they enjoy a protracted breeding season in which multiple nesting attempts can occur every 30 days, and in Southern locations, nearly year round. With all the research that has been done on lead vs non-lead bullets, there is no reason for ANYONE to use lead when hunting.
