Bear-Proof Chicken Coops: Fences, Materials & What Agencies Say

Why a Bear-Proof Chicken Coop Needs More Than a Coop

BearWise Bulletin #6, "Raising Chickens in Bear Country," says a hungry bear is strong enough to break through materials that keep out most other animals, and its heading is blunt: coops and chicken wire do not stop bears. It puts numbers on the appeal. Three chickens are about 4,500 calories, a dozen eggs about 900, and chicken feed about 1,500 calories per pound.

BearWise is a program of the Association of Fish & Wildlife Agencies. Its bulletin says a properly installed and maintained electric fence is the most reliable, effective, and long-lasting way to keep bears out of a coop and chicken yard. Colorado Parks & Wildlife points the same way, saying electrified enclosures can secure hobby livestock such as chickens.

Electric Fence Specs for a Bear-Proof Chicken Coop

These are the numbers BearWise publishes in its chicken bulletin and on its electric-fencing page. Its fencing page gives no separate numbers for coops, so the general bear-fence specs are the ones to use.

• Strands: a minimum of 3, and 5 or 6 are better.
• Lowest wire: 7 to 9 inches above the ground, or a few inches lower to also keep out skunks and raccoons. Use hardware cloth inside the electric fence so chickens stay away from the hot wires.
• Highest wire: 36 to 42 inches above the ground.
• Spacing: wires 8 to 10 inches apart. BearWise says narrower spacing, meaning more wires, is better.
• Energizer: at least 6,000 volts with at least 0.5 output joules, and 0.7 joules for grizzlies.
• Power: keep it powered up 24 hours a day.
• Wire type: BearWise says metal wire or polywire work best, and that polytape can flatten against a bear's coat and fail to deliver a shock.
• Grounding: drive a galvanized steel ground rod about six feet deep (or at an angle), and use multiple rods if you cannot reach that depth or the soil is dry.
• Upkeep: keep vegetation away from the wires so they do not short out, and test the voltage regularly. BearWise says to walk the fence every few days and listen for clicking, which can mean arcing.

The two designs differ, so ask your state wildlife agency which one it expects where you live. For the full IGBC table, see our bear-proof beehives guide, and for more on fences in general, see our electric fence guide.

BearWise says a portable solar electric netting fence can protect foraging chickens from bears during the day, but it is not a permanent solution. Colorado Parks & Wildlife adds a caution: a fence that is not working can become a tangle hazard for wildlife, so only install one you will keep up.

Coop Materials and Siting: What Agencies Actually Specify

The agency guidance on the coop itself is short. BearWise says to choose a sturdy coop with a strong roof, to site it away from overhanging trees and dense cover, and to keep the coop area and yard free of other attractants and hiding places. It does not give a wire gauge, mesh size, or burial depth, and we did not find an agency source with bear-specific numbers for those, so we are not printing any.

Two things BearWise does say about materials: ordinary coops and chicken wire do not stop a bear, and motion lights and noisemakers are not long-term solutions. Treat the coop as protection from the smaller predators and the fence as the answer to the bear.

Chicken Feed and Eggs: Store Them Like Trash

BearWise says to store feed in a bear-resistant container or inside a sturdy, locked building, and not in the coop or on the porch. It adds that plastic tubs will not keep bears out. Colorado Parks & Wildlife says chicken feed and compost left out unsecured will attract bears, and that securing them matters as much as protecting the birds.

BearWise does not name a certified feed container. If you want a product with a certification behind it, certified bear-resistant food storage lockers and containers are listed in our certified products database, alongside bear-proof enclosures and bear-proof trash cans. Check each listing for what it was tested to hold, since a certification covers the tested product, not every use.

Closing the Coop at Night

BearWise says to lock all access doors and windows in the coop at night, and that automatic locks are a good option. Colorado Parks & Wildlife recommends putting livestock in enclosed sheds or barns at night and closing all outbuilding doors so bears and other predators cannot get in. CPW also suggests checking in early spring that your coop is ready for bear season.

Is Any Chicken Coop Certified Bear-Proof?

Not that we could find. We checked the Interagency Grizzly Bear Committee (IGBC) certified products list (the October 22, 2026 edition) and the black bear approved-products page from the Wildlife Management Institute (WMI) testing program. Neither lists a chicken coop, a poultry pen, or a hen house. The IGBC list does include one beehive enclosure, covered in our beehive guide.

Check Local Rules Before You Build

BearWise says to ask your HOA, community, or county about any regulations before getting chickens or installing an electric fence, and Colorado Parks & Wildlife notes some local codes prohibit electric fencing. Some state wildlife agencies also help with fence design, loan fencing, or offset costs, per BearWise, so call yours before buying anything. See bear attractant laws by state for the wider rules, and our broader guide to feeders, coops, beehives, and compost.
