My silly young turkeys ate polk salad yesterday. I let them out of their coop to free range and have some greens and found them tearing into polk salad. Well for humans we can eat polk salad but it has to be specially prepared or it is poisonous. They seem fine today. My hen was chowing down on my canas too. I also have a black walnut tree in my yard very close to their coop and there is poison ivy growing on it. Are there any plants I should really worry about? My little flock eats everything!
