My chickens free range. I live on a farm that decades ago raised "hemp" for rope for the war effort, is what my Dad always said. He tried to kill it as it is listed as a noxious weed here in Minnesota since the 50's. I have tried to kill it since we have been here. Before anyone thinks they can come and harvest it. DO NOT EVEN THINK ABOUT IT. I have never smoked marijuana and never will, no one will smoke this..... Now the question: My chickens are eating the buds and leaves off the plants... Can I still sell them as non-medicated birds?
