I went into the enclosed yard today to give my 2, 7 week old chicks some fresh water and food and noticed they had eaten all their food, but wouldn't come to me... When I picked up the feeder I found a whole right behind it. darn moles found the new chicks and their food. I placed some chicken wire on the floor of the yard and some heavy rocks that are already around the perimeter on top of the wire. I wish they were older so they would just eat them. I hate walking though the yard and stepping into a mole hole. I just know one is gonna bite me. Oh and I do have chicken wire burred around the outside of the yard to keep things from diggin in, Guess I didn't go deep enough.
