I wasn't sure if this went here or not so I apologize but I just couldn't find a better place to post it. I want to start letting my girls out to free range a little each day, but I have a HUGE weed problem in my yard. I know that the chickens will enjoy the weeds and the bugs hiding in the weeds, but I'm worried the weeds might make them sick. I have two unknown weeds that are very common in our yard, and I have green amaranth and silver leafed nightshade. I'm mostly worried about the silver leafed nightshade since I know it is a toxic plant. How toxic, I don't know, but I wouldn't eat it myself, for sure. So the heart of this question is, can I free range my chickens with mystery and one known to people toxic weed, or must I eradicate the weeds first? (Which pretty much means they will never be free range because the silver leafed nightshade has been a five year long battle and we are losing).
