I have always been of the 'live and let live' mind-set, but I'm having a hard time coexisting with snakes. They come into the nest boxes at any time of the day and scare me and the hens. The hens won't lay when there is a snake hidden in the straw beneath them. I have thought it over and decided that I can't let the snakes get too comfortable. It's like feeding pigeons in a city park - the more food you put out, the more pigeons you get, because the pigeons are sensing 'hey, this is a good place to hang out and raise a family,' due to all the readily available food. Same thing with the snakes. They are living in the wild, but our chickens are domesticated and being kept by us. The snake only sees a easily obtained meal, always placed in the same spot at around the same time everyday. If I don't deter the snakes, they'll be setting up house and raising lots of little snakes. It is nature in action, but as our side of the equation isn't exactly 'natural' we must set some road blocks i.e. keeping area cut back, removing obvious hiding places, removing snakes if necessary. I try not to kill snakes, but sometimes you can't get a good look at the head or see enough of it to identify it as venomous or not and you know if it gets away it will hide somewhere else and possibly bite the next person who finds it (your child, for example). In those instances, I feel I can't take a chance leaving a dangerous snake around the house. We have a swamp and pond on the property and there are cottonmouths and banded water snakes that mimic them in coloration. Usually, it's rat snakes in the coop.
I am wondering however, if snakes coming to the hen house is a seasonal thing. We've found most 'pests' to be seasonal around the farm house. There is the season of giant garden spiders hanging across every window, the season of blue green beetles in the water trough. I haven't had my hen house for a full year yet, so I am hoping the snakes are a seasonal thing. If they are, I will try to look the other way when I see the ones I can identify as safe. If anyone knows about this, please let me know. Thanks
