700+ sq feet will still be denuded by them. I am using an electric easily moved fence to move them around. Even with that, they poop and step in it, making 'pancakes' which then dry and prevents the grass underneath from getting light and growing. I am going out today to rake the area we moved them off of yesterday to break up the layer of squashed poop on the top.
In the summer I try to have them out at pasture as much as possible, and they have access to three acres at that point. This year will be a little different as I am redoing one of the pastures.
Oi. Goose management.
If mine could, they would also sit on the porch. I have two in quarantine right now (new additions) and I let them in my backyard to graze. They did graze some, then came on the porch, sat in front of the sliding glass door, and occasionally rapped on the glass. Drove the dogs up the wall.
Geese are fantastic on pasture,.. and terribly messy in close quarters.
