Fencing
A well-built net or woven-wire fence can be 100-percent effective protecting pigs, poultry and sheep from coyotes. The fence should be at least 7 feet high to keep coyotes from jumping over it.
An outward slant to the wire at the top can be added to keep coyotes from climbing over, and an apron of wire extending outward from the bottom will keep them from digging under the fence. If the apron isn't used, a few well-placed snares or traps should catch the occasional coyote that digs under the fence.
A shorter, woven-wire fence can be made taller by attaching extensions to the posts and adding extra wire.
A high-tensile electric fence can serve as both a livestock and predator-proof fence if it is built to the right specifications. Contact a fencing company for specific details.
Initial costs for this type of fence are comparable to or even lower than a woven-wire fence with barbed wire at the top. Beginning with a hot wire at the bottom, the fence should have at least 7 strands of alternating hot and ground high-tensile wire. Be sure the wires are stretched tight.
The fence must be maintained to ensure there are no washouts that will allow coyotes to crawl under without getting shocked.
Installing a single electric wire near the bottom of the fence to keep coyotes from digging or crawling under the woven wire is a waste of time and money. A high-tensile predator-proof fence built to specifications is the best option. Fences can be cost effective for small enclosures but may prove expensive for large pastures. In the case of high-dollar exotic animals, a high fence or high-tensile electric fence should be considered. Losing a few expensive animals could quickly justify the expense of a predator-proof fence.
