I have seen my chickens go after snakes, mice, moles and chipmunks. I watched them go after a mouse once. One grabbed the head, one the back and they pulled the thing in half. A third chicken ran in and got the guts. It was shocking to watch. The mouse didnt have a chance. They get any of the chipmunks and mice that I catch around the house and yard. They are omnivores. I will also feed them any old meat that has been in the freezer too long. We do feed them all the weeds and veggies out of the garden as well as the an organic layer feed. I want to try feeding them maggots but the coop is too close to the house and my wife wouldnt like the smell.
out of curiosity do you feed them old chicken meat too?
