We have a black rat snake that keeps visiting our coop every couple of days. I find him in the nest box with an egg or two. I'm pretty sure its the same one that killed 2 of my chicks a month ago. We have caught it multiple times and take it away - each time farther away, but it keeps coming back. Last time I dropped it off on a country road about 4 miles away...it hasn't come back yet, but I'm wondering if that's far enough. Does anyone know what the range of a black rat snake is?
