Consider a Livestock Guardian Animal

Solution

Introduce a livestock guardian dog (LGD) or goose to protect the flock.

Explanation

Certain dog breeds (e.g., Great Pyrenees, Anatolian Shepherd) are bred to protect livestock. Geese can also be effective 'watchdogs,' alerting to intruders with loud calls and sometimes confronting smaller predators.

Notes

Requires significant commitment, training, and expense (for LGDs). Not suitable for all situations. Introducing a guardian animal requires careful integration.
