How do you keep chicken snakes away from the coop? I have two friends who I've managed to convince into getting chickens, (Muahaha!) but they live in Texas, and are worried snakes might get into the coop. I've told them to make sure there are no holes in the coop besides the door. But they aren't convinced. I've heard that mothballs (in a container with holes) will keep them away. Are there any other methods of keeping them away/getting rid of them? All help is GREATLY appreciated. Thank you!
