It sounds like you have a solid plan to protect your chickens from foxes and other predators! Here’s a summary and some additional tips you might find helpful:
1. Underground Barrier with Chicken Wire:
- Digging Depth: A trench that is 4 feet deep is an excellent idea, as it makes it much harder for foxes, raccoons, and possums to dig under the fence.
- Chicken Wire: Bury the bottom edge of the wire at least 1-2 feet below ground level and extend it along the ground horizontally for another foot or two to deter digging.
- Cement: Pouring cement around the base of the fence can provide additional security, but ensure it’s not too thick, as it may affect drainage.
2. Securing the Fence:
- Nailing the Wire: Using nails or heavy-duty staples to secure the chicken wire to the wooden posts can help keep it in place.
- Check for Gaps: Regularly inspect the fence for any gaps or vulnerabilities where animals might dig.
3. Natural Repellents:
- Natural Scents: Using vinegar, lemon, garlic, chili, jalapeño, olive oil, or blue cheese as a repellent can help keep predators at bay. Make sure to refresh these scents regularly, as they can dissipate over time.
- Placement: Focus on applying these scents around the perimeter of the yard and near the fence line for maximum effectiveness.
4. Regular Monitoring:
- Check for Signs: Frequently monitor for tracks or signs of digging to catch any potential breaches early.
- Motion Sensors: You could also consider motion-activated lights or alarms that might scare off any approaching predators.
5. Additional Tips:
- Secure Chicken Coop: Ensure the coop itself is secure with locks and strong materials.
- Lighting: Predators are often less bold in well-lit areas, so consider adding lights around the coop.
By implementing these strategies, you should be able to significantly enhance the protection of your chickens. Good luck!
