is this a bad omen?

no reason to really kill a king snake, they kill rattle snakes. I had like a 4-5 ft rattle snake in my back yard once. I see the dog attack something on the ground and then this big long rope thing flailing around in the air call her over go look and hear this "chicka chicka chicka chicka chicka" then see the damn thing. I grabbed a back hoe and wacked it once and ran back to the house haha. It was next to a gopher hole and snuck into it and I guess out because I havent seen it since.
