This is the kind of situation I support people getting geese for as opposed to out right buying geese specifically for this purpose alone as part of the same flock.
I had geese ... once. The adults were viciously hateful toward everything else on the farm, including the kids and me. One pecked a barn cat so hard in the head it bit its own tongue almost off. I, uh, rehomed the two adults to the freezer and kept the two babies. They were cool and fun and currently are very old and living their best life - somewhere else. Big farm with a pond, not mine. I discovered geese meat is tough like truck tire jerky. Be prepared for a toileting tornado. You've heard that old saying "like **** through a goose"? Yes, indeed. Coop cleaning NEVER ends. And it's bad. They eat grass 24/7. Rank liquid green exudate results. Pretty sure they're actually bovine with feathers. They eat the grass all the way past the roots and leave a poop slimed desert in their wake. Ours free-ranged a while with a predator proof box for nights in order to fix that problem. Result? Pooped porches, trucks, driveways, gardens and outdoor plants stripped down to mud. They stand outside your windows and shriek at you constantly.
Those bamboo poles are great, especially for people who are afraid to handle geese. All you need to do is hold it.
