I am in southern California, I have been yanking long weedy grasses from the side of my house and "serving" them to my 5 chickens while they are in my backyard. They have been eating it, sometimes the grasses are long pieces and sometimes they are short grasses. Right now in the winter time the grasses and weeds are green, but there are some dry grasses from last summer in the pile I give them. I read about how some of these grasses can impact their stomaches and make them sick and potentially die. Sometimes a grass will be stuck in their mouth and they try to remove it by rubbing their beaks in the ground or they walk around with it until it falls off or another chicken pulls it off. Should I be cutting these grasses? Also, If I continue yanking these weedy grasses, I am going to run out of them sometime in March. They don't eat all of the weeds I provide, they sift through the pile selecting some grasses. I place the leftovers in the compost pile at the end of the day. I also have St. Augustine grass in the backyard which they have been eating but when they see me come in with the weeds they dart toward me almost tripping me! So, cut or don't cut?
