We went in September/October to a pond that we hunt that holds lots of wood ducks. We jumped 40 off of it then. We hunted it this past week for the first time and saw ZERO wood ducks. Had 3 gadwalls come in and that was it. It was VERY hot the morning we hunted, but I don't know if that matters. I figured they would hang around. At least some of them? Any ideas?
