Lots of people think I'm crazy, but I try to leave the Copperheads. Unless they show aggression, I leave them alone. They are great for killing the 'possum sized rats running around our hay.
I visited the snake house at Texas A&M University - Kingsville and learned that snakes are like people - some are flat out mean and aggressive and some just want to be left alone. They run the gambit. And that is all in the same species. However, I've never seen a non-aggressive cottonmouth.
I remember trying to get a Copperhead away from where I was working. I picked him up with a stick and flipped him into the brush several yards away. Son of a gun came back. I flipped him over to the brush 3 more times and he came back 3 more times. Then I got the machette off the tractor. Like in Tombstone - Doc Holiday says "Ringo only wants revenge." Wyatt Earp says, "revenge for what?" "For being born." Some creatures were born to die.
