Overview: Colorado Backyard Chicken Laws: Permit Requirements, Flock Limits, and Rooster Bans
Colorado law strongly favors municipal home rule for land use regulation, so there is no state statute that uniformly permits or prohibits backyard chickens.
The Colorado Department of Agriculture oversees poultry health under the Colorado Livestock Disease Control Act (C.R.S. 35-50-101), but the real authority to allow or restrict chickens lies with Colorado's 272 municipalities.
Denver permits up to 8 hens and 2 dwarf goats per household with a free permit.
Boulder allows up to 8 hens with no roosters.
Colorado Springs permits chickens with a 6-hen limit in most residential zones.
Fort Collins permits 6 hens with a 15-foot setback.

State Law Analysis: Colorado

The Colorado Pet Animal Care and Facilities Act (C.R.S. 35-80-101) primarily addresses commercial operations but contains disease reporting requirements applicable to all animal owners.
