Current situation

What the agency's own pages and tables showed when we checked, with the line each comes from.

Bringing birds or hatching eggs into Wyoming

CVI or NPIP 9-3 for every bird (CVI valid 30 days, sent to WLSB within 14 days). Exhibition, resale, production or breeding birds from a pullorum-clean flock or tested negative within 30 days. Hatching eggs from pullorum-clean sources and not from quarantine or disease control areas without State Veterinarian permission. No HPAI-specific entry condition; WLSB adds no New World screwworm requirement beyond USDA's playbook.

What the entry rules say
  • “Originate from a hatchery or breeding flock classified as Salmonella pullorum clean under the National Poultry Improvement Plan (NPIP) or another state animal health official-approved plan.”

We found no bird-flu order covering Wyoming or any of its areas today. Its standing rules for bringing birds in and showing them still apply.
Can I take my chickens to a poultry show or swap in Wyoming?
We found no current order on poultry shows or sales in Wyoming on October 15, 2026. That is what the official pages showed, not an all-clear; call the Wyoming Livestock Board at 307-777-7515 before an event.
What do I need to bring chickens or hatching eggs into Wyoming?
CVI or NPIP 9-3 for every bird (CVI valid 30 days, sent to WLSB within 14 days). Exhibition, resale, production or breeding birds from a pullorum-clean flock or tested negative within 30 days. Hatching eggs from pullorum-clean sources and not from quarantine or disease control areas without State Veterinarian permission. No HPAI-specific entry condition; WLSB adds no New World screwworm requirement beyond USDA's playbook.
Who do I call about sick or dead birds in Wyoming?
Wyoming Livestock Board (WLSB), State Veterinarian at 307-777-7515 (business hours). Report sick or dying birds there or to USDA at 1-866-536-7593. This page is not veterinary advice; follow your state veterinarian.
How current is this page?
We read Wyoming Livestock Board (WLSB), State Veterinarian's notices on October 14, 2026. Whether each order is in force is worked out from its dates every time the page is rebuilt, at least once an hour, so an order never shows as in force after it ends.

We read each document ourselves and last checked this page against them on October 14, 2026. Where they disagree, we show you the disagreement instead of picking a winner quietly.

What we couldn't confirm
  • WLSB's import rule (rules.wyo.gov, Chapter 8; the 10/29/2025 date is read from the RefNum) was not read; the entry rules come from WLSB's poultry page.
  • WLSB's page applies the quarantine-area bar to hatching eggs; whether live birds from a disease control area are also barred is not stated on the page.
  • WLSB's reportable list PDF interleaves species columns; avian influenza is also stated as reportable on the HPAI page, which is the quote used.
  • rules.wyo.gov emergency rules were not checked.
  • APHIS detections: USDA's own Tableau export (publicdashboards.dl.usda.gov), filtered to Wyoming by the fetcher.
