Wind, cold and open space in Wyoming
Wyoming has the fewest people of any state and a lot of open land, so many keepers live on rural parcels with few rules. In towns like Cheyenne, Casper, Laramie, Gillette and Sheridan, the city code decides. Many towns allow a limited number of hens and restrict roosters. You may also need a permit. Outside city limits, county zoning applies, and agricultural land usually allows poultry. Subdivisions often have covenants, so read yours.
Building for Wyoming weather
Wyoming is high, dry and windy. Winters are cold and long, and the wind can be relentless, especially in the southeast around Cheyenne and Laramie.
- Block the wind. Use a windbreak and face the door away from the prevailing wind.
- Anchor everything. Light coops and run covers will blow away.
- Dry, ventilated coop. Vent near the roof, not at roost height.
- Heated water. Water freezes fast in wind and cold.
- Sun. UV is strong at altitude. Shade part of the run.
Choose cold-hardy breeds with small combs. Wyandottes, Brahmas, Chanteclers and Buckeyes are good choices.
Predators on the high plains
Coyotes and red foxes are found statewide. Raccoons and skunks live in towns. Hawks, owls and golden eagles hunt open land. In mountain areas, bobcats, mountain lions, black bears and grizzlies are present. In bear country, store feed indoors and use electric fencing. Our guide on predator proofing in Cheyenne covers the basics.
Bird flu and the Livestock Board
In Wyoming, animal health is handled by the Wyoming Livestock Board, which works with the state veterinarian. Do not wait to report sudden deaths or bird flu signs. Wild ducks and geese use Wyoming's rivers and reservoirs during migration, so keep them away from your flock. Get NPIP chicks and give new birds a quarantine period.
Selling eggs in Wyoming
Wyoming's Food Freedom Act is known as one of the most open direct-to-consumer food laws in the country. It may cover some egg sales from your home or farm, but rules can change and details matter. Check with the Wyoming Department of Agriculture before you sell.
Wyoming checklist
- Check city code or county rules, plus covenants.
