I have (had) 4 indian runners and 2 were just found dead. 1 with its head completely off and the other with a broken neck and half eaten. They have been in the same location for 2 years with no problems. I have neighbors on all sides of my back yard and the ducs have a raised house and shade area. I leave them out at night because I have never had problems in 2 years and they always put them selves to bed in the house at night. Any idea what could have done this in my type of area? I know I will be locking my 2 that are left in the house each night now.
