Any tips? I've got a 2 acre lake in one stubble field that has a few hundred greylags and Canadas on & I don't want them stripping off the osr half a mile away. I hate gas bangers and want to keep them for pigeons later on. Rockets? Day + night rope bangers? Luckily there's a chap living on that farm who has shot a few with a rifle which keeps the rest on their toes. There is evidence of the geese landing on the rape crop but not grazing it yet. I'm paranoid about them devouring it on a full moon.
