Well... Had to call the sheriffs dept out yesterday. Got home and ALL of my adult birds except one were gone. I'm furious. They dug under my fence. The top of my run is covered and it has hardware cloth about a foot and half up from the bottom to keep the chicken wire from being chewed thru so what do they do? They dig under. I'm going to be putting electrical wire around the bottom of the pen. It's ridiculous. I haven't lost birds to predators in about 3 years.
