Wyoming does not set a hen number. Towns do. Cheyenne and Casper cap flocks at 6 hens and bar roosters. Laramie allows up to 12 birds and does not bar roosters in the poultry section. Sheridan allows 2 to 5 hens. Gillette allows 5 hens. Jackson does not allow poultry in town. Rock Springs allows hens with a $25 permit and no roosters.
⚠️ Important: Wyoming ordinances may change without notice. Always verify the current rules with your local jurisdiction and any HOA efore you build your coop.

Selling Backyard Eggs in Wyoming
The Wyoming Food Freedom Act lets you sell eggs from birds you keep without a state food license. Hand them to the buyer in Wyoming and say the eggs were packed at home and are not state-inspected. Cities may still treat a regular egg stand as a home business.
Wyoming Poultry Slaughter Rules
Birds you raise can be processed at home for your household and unpaid guests. That meat stays off the market. A separate Food Freedom cap covers up to 1,000 of your own birds a year sold in-state. Several city codes forbid processing inside town limits.
