How long can button quails live to be?

They seem to average 3 to 5 years for males (though I've heard of as long as 9), and 2 to 4 years for females. The hen's lifespan depends a lot on how much she has had to lay eggs and whether she has had adequate nutrition to keep her from "depleting" her body's resources. Protein, calcium and vitamin D are essential for female button longevity. Of course, any button who lives in a stressful environment, or gets injured seriously or repeatedly, is going to have a shorter life-expectancy.
