Install secure fencing

Solution

Use sturdy fencing around the geese's enclosure, at least 4-5 feet high.

Explanation

Woven wire or electric fencing can deter ground predators. Fencing should be dug into the ground or have an apron extending outwards at the bottom to prevent digging under. Mesh size should be small enough to prevent smaller predators like raccoons from squeezing through.

Notes

Electric fencing can be very effective but requires maintenance.
