Should you have a bird feeder if you keep backyard chickens?

The short answer

• In the United States, USDA Wildlife Services tells poultry keepers not to feed wild birds anywhere on the property, including around the house, because seed, suet and corn bring wild birds and rodents in often.
• In Canada, Environment and Climate Change Canada calls feeders unlikely to spread bird flu, but says to remove them from areas open to poultry and to remove outdoor food that attracts wild birds if you keep poultry.
• The songbird pathogen with a measured chicken link is Mycoplasma gallisepticum, the cause of house finch eye disease: chickens in direct contact with infected finches for 10 weeks seroconverted at 80 percent, and none did across wire.
• Do not let chickens forage under a wild bird feeder, and do not shovel feeder spill into the run. The ground there is where wild birds land, feed and leave droppings.
• If you keep a feeder anyway, put it and its spill zone where the flock can never walk, keep chicken feed and water inside the coop, and take the feeder down in migration and at any local bird flu detection.

In the United States, no: USDA's Wildlife Services tells anyone keeping poultry, "Do not feed wild birds or other wildlife on the property, including areas around houses or offices." In Canada, a feeder is allowed, but Environment and Climate Change Canada (ECCC) says to "remove bird feeders from areas that are open to poultry and other domestic animals." What both object to is a yard that pulls wild birds and rodents onto the ground the flock uses.

What each agency actually says#

Why two answers circulate#

"Feeders are fine, keep wild birds from your chickens" is the Canadian position; "take feeders down" is the American one. Read the ECCC page to the end, though, and the gap narrows. Its line calling feeders unlikely to spread bird flu is for households in general. Its line for poultry keepers says to remove outdoor food that attracts wild birds, and a feeder is exactly that. The US says no feeder; Canada says no feeder anywhere it touches the flock's space.

Pathogen by pathogen#

Bird flu dominates the coverage, but it is not the disease with the clearest songbird link.

Mycoplasma gallisepticum: the one with numbers#

House finch eye disease is caused by Mycoplasma gallisepticum (MG), which was a poultry pathogen first. An Iowa State abstract describes it in poultry as causing respiratory disease and conjunctivitis, "which can result in decreased egg production."

Three studies put numbers on the jump back toward chickens:

• Stallknecht and colleagues, 1998. Chickens in direct contact with naturally infected house finches caught the finch strain: 80 percent seroconverted (20 percent PCR, 30 percent culture positive). It took 10 weeks of direct contact, no clinical disease was seen, and chickens across wire or across the room showed no infection. Minimal biosecurity restricting direct contact "should significantly reduce the potential" for transmission, the authors concluded.
• O'Connor and colleagues, 1999. A finch isolate produced milder lesions than the R-strain in chickens and turkeys, and only R-strain chickens died. It "may infect domestic poultry species but causes only mild disease."
• Daves, 2016. An Iowa State honors poster tested 46 chickens in five backyard flocks near Ames: 13 percent, in 3 of 5 flocks, were likely exposed, and flocks at sites with house finches "tended to show more MG exposure." The author calls it preliminary.

So the risk is real but slow and contact driven. A finch at a feeder across the yard, never touching the run, is not a scenario anyone measured.

Salmonella and mites#

APHIS lists Salmonella and Campylobacter among the bacteria wild birds, rodents and insects bring toward poultry, and salmonellosis is the outbreak most likely to hit a seed feeder, in pine siskins especially (see bird diseases at feeders). No source we read measures it moving from feeder songbirds to a backyard flock. The firmer link is rodents: spill feeds the rats and mice that also visit the coop.

Mites do not come from feeders. The two species that bite people indoors are the northern fowl mite and the chicken mite, and they come from nests, as set out in bird mites and bird feeders. The feeder matters only if it feeds house sparrows and starlings that nest in the coop; APHIS says to sweep away old nests before nesting season.

Can chickens eat the seed under the feeder?#

Not off that ground. The spot is the problem, not the seed: it is where wild birds land, feed and leave droppings, CFIA's "landing in the same area" and "sharing feed" in one square yard. USDA adds that "even a tiny amount of feed is a meal for a wild bird or rodent."

• Never pass spill or old feeder contents to the flock. Moldy corn and peanuts are an aflatoxin hazard to chickens: see moldy seed.
• Fresh seed from a sealed bag goes inside the coop like scratch, by the BC rule: only as much as the birds clean up.

If you keep a feeder anyway: a layout rule#

1. Feeder and spill zone outside every area the flock can reach. The far side of the house is better than the far side of the run. Plan for the drop zone, not the pole: seed waste and mess covers what lands below.
2. Roof the run, so feeder birds cannot land where the chickens are: CFIA's first route.
3. Chicken feed and water inside the coop, per BC, and all seed in sealed containers: storing birdseed covers metal cans.
4. Feed hull-free seed and skip ground mixes. Sunflower hearts leave no hulls. USDA names corn specifically, and cracked corn on the ground draws the doves and pigeons you least want.
5. Clean up spill daily, APHIS's "right away."
6. No bird bath near the run. Shared water is one of CFIA's named routes; see bird baths and water.
7. Coop chores first, feeder second, then wash. BC's rule is clean hands, clothing and footwear before and after handling birds.
8. Take it down through spring and fall migration, at any bird flu detection in your area, and at the first finch with crusted eyes; then clean it before it goes back.

A pause costs the wild birds little: birds do not depend on feeders, and native plants keep them in the yard without seed.

Where this page stops#

• Ducks and geese with a pond. Waterfowl are the main bird flu source, and a pond draws more than any feeder. BC's first rule is to fence poultry off ponds and streams.
• Commercial flocks follow their site biosecurity plan, which overrides this.
• The MG evidence is small and old: two lab studies and one student poster. It shows contact transmission is possible, not how often it happens in backyards.
• Local law. Some cities regulate feeders on their own terms; see bird feeder ordinances.
• Predators are a separate coop problem: see foxes.

Frequently asked questions#

Can I have a bird feeder if I have chickens?

In the US, the agency answer is no. USDA APHIS Wildlife Services says not to feed wild birds or other wildlife on a property with poultry, including areas around houses. In Canada, Environment and Climate Change Canada says to remove feeders from areas open to poultry and to remove outdoor food that attracts wild birds if you keep poultry. If you keep one anyway, the feeder and the seed it drops must be somewhere your chickens can never walk.

Do bird feeders spread bird flu to chickens?

Not directly, as far as the agencies say. Environment and Climate Change Canada calls feeders unlikely to spread highly pathogenic avian influenza and the outbreak risk in feeder species low. The concern is indirect: feeders bring wild birds and rodents to the property more often, and spilled seed draws them to the ground. The wild birds that agencies name as carriers are ducks, geese, gulls and shorebirds rather than finches and chickadees.

Can chickens get house finch eye disease?

They can be infected. In a 1998 study in Avian Diseases, chickens kept in direct contact with naturally infected house finches seroconverted at 80 percent, but only after about 10 weeks, and none showed clinical disease. Chickens across wire or across the room showed no infection. A 1999 study found the finch strain caused milder lesions than a standard poultry strain and no deaths.

Can chickens eat wild bird seed?

Do not let them eat it off the ground under a feeder, because that is where wild birds land, feed and drop. Moldy corn or peanuts from a damp feeder should never go to chickens at all, because of aflatoxin. If you want to give fresh seed from a sealed bag as a treat, give it inside the coop like scratch, and only as much as the birds clean up, which is the British Columbia agriculture ministry's rule for scratch.

How far should a bird feeder be from a chicken coop?

No agency source we read gives a distance, so we do not invent one. The usable rule is not feet but access: the feeder, the ground it drops seed on and any bird bath must be outside every area the chickens can reach, and the run should be roofed so feeder birds cannot land in it. In the US, USDA's advice is to have no feeder on the property at all.
