First one was the common 2x4" grid welded wire fence. A distressed goose's wing got stuck in the opening. Second one was an electric poly netting portable coral I used to let the geese graze at strategic locations. I never electrified the netting. Somehow, one goose or gander got terribly entangled in the netting. I really liked the portability and this did work fine for 6.5 months. Poly netting might be just fine for a more permanent installation. I already planned to add a field perimeter fence. This will be woven galvanized steel material. Would be such a huge help if the geese could graze the fence line as well, but those openings have to be the correct size and tension. Anybody else had a "did not work" setup? Or was able to make alterations that worked?
