After backtracking we decided to quit wasting time trying to find a way into a new meadow and go enter in the area we were familiar. We had about an hour of light left when we dropped our packs and started to look for signs of birds. We found a highway of tracks and headed to the new meadow. In the darkness of night we set up our decoys among the highway of tracks and left them there so we wouldn't have to bother in the morning.
We backtracked and would try to flank them again. We managed to get to about 50 yards of them only to be spooked by two numbnuts that decided to blast through the meadow.
