I've heard that the venom in young rattlesnakes is not more poisonous, just more concentrated. I haven't been willing to test this theory. I do find a lot of young bull snakes in the yard, these I leave alone. And occasionally, I find young rattlesnakes. If I can, I'll relocate them. They mostly eat rodents, and that's alright by me. One year I had a rock chuck come up to the fence and totally creap-out my blue healer. She didn't know what to make of it, so she headed for the house. I, on the other hand, tried to scare it off. I yelled at it, kicked the fence, and went so far as to fire a round into the ground next to it. Did it run away like I thought it would? Heck no, it just stood on its hind legs and hissed at me. The next round went through the lungs & heart.
