Hey spark that is exactly what is starting to happen in my pond just as you described. My pond is 3/4 to 1 acre. The other day we were out there and the feeder went off fish hitting the food like crazy. Throw a worm and bobber in there and not a bite!! Fish jumping all around the bobber I couldn't believe it?? Maybe it does have something to do with size of pond? I don't know I am also using AM 500/600. The fish almost act like they are getting lazy and it's to much trouble to go after your bait!! Dang it man. If it's not one thing it's another!!
The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
