Feeding chickens kitchen scraps safely in Australia
What can go in the scrap bucket, how much, and the rules on meat and eggs.
Kitchen scraps are a treat on top of a complete feed, not a diet. Most fruit, vegetable and plain grain scraps are fine. Meat, anything that has touched meat, and in Queensland eggs as well, are a legal question as well as a health one. This page covers the rules first, then the scraps people ask about most. For the full food list, see what chickens can eat.
The rules: meat, eggs and swill
Queensland. It is illegal to feed swill to any poultry, and Biosecurity Queensland says the ban covers pet poultry and hobby flocks. Swill is anything that contains, or may contain, a mammal or bird carcass or material from a mammal or bird, including meat, eggs, blood and faeces, and any food that has been in contact with those, including scraps from a home kitchen. Penalties include fines and imprisonment.
What Queensland allows: fruit, vegetables and cereals; bakery or vegetable scraps that contain no egg, meat or meat products and have not touched them; Australian milk and milk products; and meat, blood or bone meals bought from a produce store or feed merchant.
Other states and territories. The swill rules we found for New South Wales and Victoria are written for pigs (prohibited pig feed) and for cattle, sheep and goats (restricted animal material). We found no equivalent ban for backyard poultry in other states' published guidance as at October 2026. That is not the same as permission, and rules change, so check with your state or territory agriculture department before feeding meat scraps. Our advice everywhere is not to.
Why it matters. Biosecurity Queensland says swill can carry viruses that cause serious poultry diseases such as Newcastle disease and infectious bursal disease. Biosecurity Tasmania notes that kitchen scraps can carry bacteria and viruses that affect poultry.
How much
About 10 percent of the diet at most (UF/IFAS Extension), or no more than the flock finishes in about 20 minutes (US Cooperative Extension). Give scraps in the afternoon, after the hens have had their fill of layer feed in the morning, so the scraps top up the diet rather than replace it. Biosecurity Tasmania warns that hens living on scraps run short of calcium, which shows up as thin shells and weak bones.
Fresh, not rotten
Feed scraps the day they are made. Rotting food breeds the bacteria behind botulism, and maggots on rotting food pass the toxin on (MSD Veterinary Manual). Mouldy bread, fruit, nuts and grain carry mycotoxins. Scraps left lying overnight bring rats and mice (Biosecurity Tasmania). If it is too far gone for you to eat, it goes in the compost, not the run.
Salt, sugar and fat
Hens are small, so a salty leftover is a big dose. Salt poisoning in poultry is most likely when water runs short (MSD Veterinary Manual), so scrape sauces, gravy and anything salty into the bin, and keep the waterer full. Sugary and fatty food such as cake, biscuits, chips and takeaway fills the crop without the protein and calcium hens need.
Dairy
Chickens do not make lactase, the enzyme that breaks down milk sugar, so a lot of milk gives them loose droppings. Small amounts are fine: US Cooperative Extension notes that sour milk can be fed, and a spoonful of plain yoghurt or a crumb of cheese is a treat. Australian milk products are allowed under Queensland's rules.
The scraps people ask about
Meat No
Why: Illegal for all poultry in Queensland, backyard hens included. Biosecurity Queensland says swill can carry poultry viruses such as Newcastle disease. We found no equivalent ban in other states, but meat scraps also spoil fast.
How to serve: Not recommended anywhere. See the kitchen scraps guide for the rules.
Chicken (meat) No
Why: Feeding poultry meat to poultry is illegal in Queensland and a disease risk everywhere.
How to serve: Do not feed it.
Tuna and other fish In moderation
Why: Plain fish is a protein treat. Tinned fish in brine is salty.
How to serve: A spoonful of tuna in spring water, rarely. Queensland's law names mammal and bird material; fish is not named, but anything that has touched meat or egg is.
Eggs In moderation
Why: Cooked eggs are good protein, but feeding eggs to poultry is illegal in Queensland.
How to serve: Outside Queensland: cooked and chopped, never raw or whole, so hens do not learn that eggs are food.
Eggshells In moderation
Why: A calcium source, but eggs, shells included, are on Queensland's prohibited list.
How to serve: Outside Queensland: dried and crushed so they do not look like eggs. Oyster shell works everywhere.
Bread In moderation
Why: Filling but low in protein and calcium. Mouldy bread is never safe. In Queensland, only bread with no egg or meat in it, and no contact with them, may be fed to poultry.
How to serve: A small amount, broken up. Never mouldy.
Pasta In moderation
Why: Plain cooked pasta is safe but mostly starch. Egg pasta is an egg product, so in Queensland it may not be fed to poultry.
How to serve: Plain and cooked, no sauce, in small amounts.
Breakfast cereal In moderation
Why: Plain cereals are safe but mostly starch. Sugary, salty and chocolate cereals are not suitable.
How to serve: A small handful of plain, low-sugar cereal, dry or softened.
Cheese In moderation
Why: Safe in small amounts. Chickens do not make lactase, the enzyme that digests milk sugar, and most cheese is salty.
How to serve: A crumb or two, rarely.
Milk In moderation
Why: Small amounts are fine; US Cooperative Extension notes that sour milk can be fed. Chickens do not make lactase, so a lot of milk loosens droppings.
How to serve: A splash mixed into mash, now and then.
Yoghurt In moderation
Why: Plain yoghurt is safe in small amounts. The lactose limit is the same as for milk.
How to serve: A spoonful of plain, unsweetened yoghurt, rarely.
Butter No
Why: Not toxic, but it is fat and usually salt, with nothing a hen needs.
How to serve: Do not feed it.
Ice cream No
Why: Sugar, fat and lactose together, and some flavours contain chocolate.
How to serve: Do not feed it. Frozen fruit does the hot-weather job better.
A simple scrap bucket routine
- Keep a lidded container for fruit, vegetable and plain grain scraps only.
- No meat, and no plate scrapings that have touched meat or egg. In Queensland that is the law; elsewhere it is the safe habit.
- Check for the never-feed foods: avocado, onion, garlic, chocolate, coffee grounds, green potato peel, salty or mouldy food. The toxic foods guide has the full list.
- Empty it into a dish once a day, in the afternoon, rather than straight onto the ground.
- Pick up whatever is left by dark.
Common questions
Is it legal to feed chickens kitchen scraps in Australia?
Fruit, vegetable and plain grain scraps are fine everywhere. In Queensland it is illegal to feed any poultry, backyard hens included, meat, eggs or anything that has been in contact with them. We found no equivalent poultry ban in the other states' published rules as at October 2026, but check with your state or territory agriculture department.
Can chickens eat meat scraps?
Not in Queensland, where it is illegal. Elsewhere we found no ban, but we advise against it: meat spoils fast, and Biosecurity Queensland notes that swill can carry poultry diseases such as Newcastle disease.
Can I feed my chickens their own eggs in Queensland?
No. Queensland's definition of prohibited poultry feed includes eggs, and food that has touched eggs. Use oyster shell for calcium instead of eggshells.
How much kitchen scrap can chickens have?
About 10 percent of the diet at most, or no more than they finish in about 20 minutes. Pick up the leftovers so they do not rot.
