Hi, I'm worried about keeping snakes and other predators out of the coop and run I'm working on in northeast Oklahoma. There's a big creek running through my backyard with snakes, and coyote dens on the other side of my fence. We even have wolves that I see about once a year, and every kind of predator. They walk along the ceek which traps the scent of any animal in my yard, so the predators are down wind and can't be smelled by the prey animals in my yard, but they can smell my animals like a buffet line.
I've read that only 1/4" hardware cloth fastened with bolts and washers instead of staples can keep all predators and snakes out bc coons can reach through the 1/2" mesh and it's not hard to pull out staples. I'm pretty sure some snakes and weasels can squeeze through 1/2" mesh. Also chicken wire is useless for keeping out predators.
I also read interesting articles about stopping snakes written by Australians, who have even a worse snake problem than we do in the USA. Their dogs are often killed by snakes. They mentioned all different kinds of snake traps they build, especially scrunched up bird netting around the base of coops and runs extending a couple of feet up the side so snakes get stuck in it. Also using sulfur around buildings, and making traps with half open cans of milk with the lid pushed in so the snake can't pull it's head out of the can. I've been meaning to buy snake proof boots from snakeboots.com since other kinds of boots don't really protect.
Sometimes snakes bite people or animals who accidentally get too close to their hiding place, even if you don't step on them. Example: a lady walks into her barn or shed and feels something bump her leg, then minutes later she's feeling the venom. Some snakes are so agressive that one chased my neighbors until they all jumped on top of a picnic table, then threw their son off the other side and told him to run for help. Lol Another snake chased a neighbor on his riding lawn mower. I think they were cotton mouths.
Anyhoo, I'm feeling overwhelmed by predator pressure. I'm thinking of lining the wood floor and inside of my shed with 1/4" mesh, using wolf pee or bear pee around my run, plus those solar blinking lights, bird netting around the base to trap snakes, and sulfur, a baby monitor, electric fencing, you name it. Lol. I'm just not sure how much I can afford to do all at once for startup.
I'm also thinking of keeping guineas in with my chickens since they gang up and kill snakes and would sound the alarm if predators approached.
