What is a good chicken safe herbicide? I just finished my coop/run and put in an electric fence. I have two wires around the base at 4"&10", one at 36", and one at the top. From past experiences, I know that weeds/grass will draw power out of the fence and eventually short it out. The 4" wire is going to be a problem, but I want it that low to dissuade digging. I want to have a 6" wide "dead" zone around the whole nine yards, and I won't literally salt the ground there since I may want something to grow there again it the next few hundred years. Any suggestions? I really don't want to ask someone to trim the grass around the coop on top of feeding my animals if I go on vacation. I hate spraying, but with a true mile of fence around my farm, I'm gonna have to get used to it. Just don't want to kill the chickens I'm trying to protect (bit of a difference between a cow sized critter eating a bit of roundup and a chicken doing the same).
