I am snake skiddish, and my first response was typical of my knee jerk response whenever I see a snake. But I do tend to agree with @centrarchid . I don't typically kill any snake that is not venomous AND making my yard it's territory. I wouldn't be able to abide a resident snake in my house or my chicken's house, though, because I couldn't take the strain of always getting a fright from it, so I would want to relocate it. Many of these non-venomous snakes also prey upon the less desirable snakes, such as copperheads. They truly are beneficial.
