Can you keep backyard chickens in Idaho?
Idaho cities and counties zone by ordinance (Idaho Code 67-6511), so check yours. County zoning can't deprive owners of full use of agricultural land to farm; whether that covers a backyard flock wasn't established.

Who decides where hens can live
The state law we read gives a named local body its own powers over where hens can live. What the checked sources say:
- Every city and county must exercise the powers of the chapter. A city council or board of county commissioners (the governing board) sets up zoning districts by ordinance, and within a district sets standards regulating, among other things, the use and location of buildings and structures; a county’s powers apply to its unincorporated area.
- No power in the chapter lets a board of county commissioners enact an ordinance or resolution that deprives an owner of full and complete use of agricultural land for producing any agricultural product.
No statewide permission or prohibition on keeping chickens is established by this finding. Agricultural land is defined by each county’s own ordinance or resolution, and whether a backyard flock is on agricultural land was not established. Your city council, or your board of county commissioners outside cities, sets zoning by ordinance, so check with it. This page doesn't cover local codes.
The law's own words are quoted under state rules on keeping poultry below.
How to check: Look up the local rules where you live (the ordinances, bylaws or zoning of the body named here), or ask that office, before you get hens.
A sourced reading of Idaho's state law, not legal advice. Local ordinances and zoning, HOA rules, and any local rooster or coop limits aren't covered here yet: check your local code before you get hens.

Registering as a poultry keeper
Conditions apply to this finding
Jurisdiction: Idaho
Applies to: Idaho’s permit for poultry concentrated animal feeding operations (CAFOs) under the Poultry Environmental Act (Idaho Code 25-4002, 25-4003 and 25-4011), and the Idaho State Department of Agriculture’s premises registration program.
Outside this finding's scope
- Below the sizes listed, no registration duty for poultry keepers was found in Idaho Code Title 25, chapters 2 and 40, or in the department’s Rules Governing Animal Industry (IDAPA 02.04.03); this is not proof that none exists. The permit rule covers only CAFOs built or modified after the Act took effect; how the Act treats facilities that already existed (25-4005) was not read.
What the checked sources say
- As checked on 26 October 2026, the Idaho State Department of Agriculture’s FAQ said the premises registration program in Idaho is currently voluntary.
- No one may construct, operate or expand a poultry CAFO of any size without first getting a permit from the director of the Idaho department of agriculture. A poultry feeding operation is a lot or facility where poultry are confined and fed or kept for 45 days or more in any 12 months and no crops or vegetation grow over any part of it in the normal growing season; it is a CAFO if it reaches the large or medium sizes in the Act, or if it is designated as one.
- The director may, case by case, designate a smaller poultry feeding operation as a medium CAFO if it is a significant contributor of pollutants to waters of the state.
Thresholds
- Medium poultry CAFO (chickens): 9,000 to 29,999 laying hens or broilers with a liquid manure handling system; 25,000 to 81,999 laying hens, or 37,500 to 124,999 chickens other than laying hens, with any other system.
Authority: Director of the Idaho department of agriculture (CAFO permits).
Fee: Not established from the sources checked.
The official wording

Jurisdiction: Idaho
Applies to: Idaho’s temporary quarantine power (Idaho Code 25-218), held by representatives of the state department of agriculture or its division of animal industries and by USDA animal health inspectors, together with the department’s Rules Governing Animal Industry (IDAPA 02.04.03).
Outside this finding's scope
- These powers do not in terms require birds to be kept indoors, and this finding does not establish that any quarantine or order applies now. In Idaho Code Title 25, chapter 2, which contains 25-218, the word animal or animals includes any vertebrate member of the animal kingdom, except man (25-210(2)); the rule definitions given here apply to the part of the rules they sit in (Subchapter A).
What the checked sources say
- These officials may quarantine temporarily, where found or in any convenient place nearby, any animals affected or infected with, or exposed to, any contagious, infectious or communicable disease. The owner or custodian gets written notice, and the animals may not be moved, treated, tested or disposed of except under the department’s and division’s rules.
- The rules say they apply to all owners of livestock and other animals. They define an animal as any vertebrate except man, poultry as domesticated fowl including chickens, and a quarantine as a written order (or a verbal order followed by a written one) from the Administrator to confine or hold animals on a premise or other location and stop their movement, when the animals are found or suspected to be exposed to or infected with a disease, or are not complying with the rules.
