Owning a duck in Illinois is legal, but what you have to do to keep one depends on the breed, your city or village’s ordinance, and a handful of state and federal rules on care, disease reporting, and protected wildlife. Domestic breeds like Pekins, Khaki Campbells, and Indian Runners are the simplest path. Mallards are legal too, with a federal marking requirement attached. Taking a wild duck out of a pond and bringing it home is not legal under any circumstances.
Which Ducks You Can Legally Keep
The Illinois Wildlife Code says the state owns all wild birds and wild mammals within its borders.1Illinois General Assembly. Illinois Code 520 ILCS 5 – Wildlife Code Because the Code only reaches wild species, a purely domestic breed falls outside it.2Illinois General Assembly. Illinois Code 520 ILCS 5/2.2 – Scope and Protected Species Buy a Pekin from a hatchery and the Wildlife Code is not your problem.
Wild waterfowl in the family Anatidae are listed as migratory game birds and protected.2Illinois General Assembly. Illinois Code 520 ILCS 5/2.2 – Scope and Protected Species You cannot pull a wild duck out of the wild to keep. Regulation of wildlife taking is an exclusive state power, so even home-rule cities cannot grant you permission. The statute specifically excludes the Muscovy Duck from the protected list, which is why Muscovies are often sold alongside domestic breeds.
Mallards and the Federal Marking Rule
Mallards are the awkward middle case: a wild migratory species and one of the most commonly captive-bred ducks in the country. Federal regulations resolve this with a specific exception. Captive-reared, properly marked mallards can be owned, sold, traded, and transported by anyone without a federal permit.3eCFR. 50 CFR 21.45 – Permit Exceptions for Captive-Reared Mallard Ducks
“Properly marked” is the condition that matters. The regulation requires at least one permanent marking method, and nothing in the rule permits taking live mallards or their eggs from the wild.3eCFR. 50 CFR 21.45 – Permit Exceptions for Captive-Reared Mallard Ducks When you buy from a breeder, confirm the birds are already marked or arrange marking right away. An unmarked mallard in your yard looks like a wild bird to a game warden, and you carry the burden of proving otherwise.
Other captive-bred waterfowl on the federal migratory bird list, such as Wood Ducks or Mandarins, do not get this exemption. Keeping them generally requires a federal permit from the U.S. Fish and Wildlife Service.
What Your Town Allows
The rules that most often decide whether you can actually keep ducks at your address are municipal, not state. Illinois municipalities have broad authority over land use and can regulate whether poultry is allowed in residential zones, how many birds you can have, what the enclosure looks like, and how far it sits from the property line. The rules vary sharply from town to town.
Some municipalities treat ducks like backyard chickens and allow a small number (often four to six) in residential areas with conditions. Others restrict all poultry to agricultural zones. Common conditions you should expect to run into include:
- A cap on the number of birds, sometimes with drakes prohibited to control noise.
- Setback distances between the enclosure and neighboring homes, property lines, or wells.
- Enclosure standards covering predator-proof construction and minimum square footage per bird.
- A small livestock permit or annual registration, sometimes with a fee and periodic inspection.
- In some cities, a special use permit requiring an application to the zoning board and a public hearing.
Call the zoning office or read the municipal code before you buy birds. Do not take a neighbor’s or a breeder’s word for what is allowed. Even where no ordinance mentions ducks by name, general nuisance ordinances on noise, odor, and sanitation still apply.
The Care Standard Illinois Holds You To
Once the birds are on your property, the Humane Care of Animals Act governs how you treat them. It applies to ducks the same way it applies to dogs or cats. Every owner must provide each animal with sufficient quantities of good quality, wholesome food and clean water; shelter and protection from the weather; veterinary care when needed to prevent suffering; and humane care and treatment generally.4Illinois General Assembly. Illinois Code 510 ILCS 70/3 – Owner’s Duties
The Animal Welfare Act (225 ILCS 605) is a separate statute that regulates commercial operations like pet shops, kennels, and shelters, not individual owners.5Illinois General Assembly. Illinois Code 225 ILCS 605 – Animal Welfare Act If you are keeping a backyard flock, the Humane Care of Animals Act is the one that reaches you.
Selling the Eggs
Ducks lay more than most households can eat, and Illinois regulates egg sales. State law defines “eggs” to include duck eggs alongside chicken, turkey, goose, and guinea eggs, and anyone who buys, sells, or trades eggs generally needs an Illinois Egg License.6Illinois Department of Agriculture. Selling Eggs
There is a narrow on-farm exemption. If you sell nest-run eggs from your own flock directly to household consumers, on the same premises where your flock is kept, and the buyer picks them up in person, no license is required.6Illinois Department of Agriculture. Selling Eggs The eggs must be ungraded and go directly from your property to the consumer. The moment you sell off-site, at a farmers’ market, or through a retail store, you need a Limited Producer-Dealer egg license and have to meet the grading and handling requirements of the Illinois Egg and Egg Products Act.
Disease Reporting You Are Expected To Do
Avian influenza is the big health concern for anyone keeping ducks. If your birds show signs of bird flu or any unusual symptoms such as increased deaths, reduced egg production, or respiratory distress, you are expected to report it to the Illinois Department of Agriculture at 217-782-4944 or USDA Veterinary Services at 1-866-536-7593.7Illinois Department of Agriculture. Poultry and Birds – Animal Health The Illinois Department of Public Health also publishes biosecurity guidance for poultry owners.8Illinois Department of Public Health. H5N1 Information for Livestock and Poultry Farm Owners During active outbreaks, state and federal authorities can order quarantines and depopulation of infected flocks.
Ducks also naturally carry salmonella, even when they look healthy. The Illinois Department of Public Health advises thorough handwashing after any contact with birds or their living areas, and keeping birds out of food-preparation spaces.9Illinois Department of Public Health. Salmonella
Predators You Cannot Shoot
Hawks, owls, and eagles will take ducks, and the Migratory Bird Treaty Act makes it a federal offense to kill, capture, or harm any migratory bird without a permit from the Secretary of the Interior.10Office of the Law Revision Counsel. 16 USC 703 – Taking, Killing, or Possessing Migratory Birds Unlawful Every raptor in Illinois is covered. Shooting a Red-tailed Hawk that has been raiding your flock is a federal crime.
Your legal options are non-lethal: covered runs, netting, visual deterrents like reflective tape, and secure housing during dawn and dusk when raptors hunt. A fully enclosed run is the most reliable fix if you live near woods or open fields.
Waste, Nuisance, and Liability
Backyard flocks sit below the thresholds that trigger the formal siting rules of the Illinois Livestock Management Facilities Act, but general environmental and nuisance rules still apply. If duck waste reaches a neighbor’s well or runs off into a waterway, you can face enforcement under the Illinois Environmental Protection Act regardless of flock size.11Illinois General Assembly. Illinois Code 510 ILCS 77 – Livestock Management Facilities Act Compost or dispose of soiled bedding regularly, keep it away from storm drains, and manage odor so it does not become a neighborhood complaint.
No Illinois law requires duck owners to carry liability insurance, but you can be held financially responsible if your birds damage a neighbor’s property or injure someone. Homeowner’s policies sometimes cover damage caused by domestic animals, but poultry is often excluded or needs an endorsement. Read your policy before assuming you are covered, and if you free-range the birds, fence them.
Penalties If You Get It Wrong
Enforcement runs on two tracks. Municipalities enforce their own poultry rules, with penalties that typically include fines, mandatory corrective action, or an order to remove the birds. Amounts and escalation schedules vary; check your local code.
On the state side, failing to provide adequate food, water, shelter, or veterinary care violates the owner’s duty under the Humane Care of Animals Act and is a Class B misdemeanor on a first offense. A second or subsequent conviction becomes a Class 4 felony.4Illinois General Assembly. Illinois Code 510 ILCS 70/3 – Owner’s Duties
Cruel treatment is charged separately and starts higher: a Class A misdemeanor on a first offense, rising to a Class 4 felony on a second or subsequent conviction. If the cruel treatment occurs in the presence of a child, the court adds a $250 fine and at least 100 hours of community service.12Illinois General Assembly. Illinois Code 510 ILCS 70/3.01 – Cruel Treatment Courts can also order a psychological evaluation at the defendant’s expense, and for repeat offenders and animal hoarders the evaluation is mandatory. Animal control officers and humane investigators do act on complaints, and neighbors who see ducks in poor conditions report them.
