I like the Black Snake. I enjoy seeing them around barns and out buildings. I wouldn't be too thrilled with them sharing the house, mama would not live in the same houses if she knew it. But yes the Black snake is a friend and should be relocated rather than killed. Good for you!
I relocate critters around here too. I had a chicken snake I caught in my pen that I relocated. Also raccoons and possums were moved to other locals.
