Field notes from the local park pond, written after watching the wrong bag of food go in.
The short version: bring cracked corn, frozen peas (thawed), porridge oats, or chopped greens to the pond. Skip bread, crackers, popcorn, chips and anything from the human-snack aisle. A small bag - 100 to 200 grams - is plenty for a visit; overfeeding causes more harm than feeding the wrong thing.
The four foods that actually work
In rough order of usefulness:
1. Cracked corn
The gold standard for park-pond feeding. Most poultry shops, garden centres and feed stores sell it. Ducks and geese both eat it eagerly; it’s calorie-dense enough to matter in winter; it’s cheap; and the birds finish it in a few minutes so it doesn’t sit at the water’s edge attracting rats.
Whole corn is too big for many ducks to swallow easily. Cracked corn (the kind sold for poultry) is the right size. Avoid sweet corn kernels off the cob unless you’ve cooked them - the sugars in raw sweet corn aren’t great for waterfowl.
A 50 lb bag of cracked corn costs about the same as one supermarket sliced loaf and feeds a pond for a season.
2. Frozen peas (thawed)
The single best food to bring for ducks in summer. High protein, palatable, exactly the size for a duckling, and provides vitamins waterfowl need. Buy a bag of frozen peas at the supermarket, thaw under warm water for two minutes, drain. The bag becomes a pond visit kit.
Don’t feed them frozen - they’re hard on duck mouths.
3. Rolled or porridge oats (uncooked)
Plain rolled oats - the kind you’d make porridge with, not the flavoured instant variety. Calorie-dense, easy to swallow, and birds eat them readily. Scatter on the bank, not in deep water, so they don’t disperse.
Avoid instant oatmeal sachets - the added salt and sugar is bad.
4. Chopped leafy greens
Lettuce, kale, spinach, watercress - chopped into duck-sized pieces. Mallards and geese both graze on greens naturally; offering chopped greens is the closest you can get to a natural diet. Great for ducklings.
Avoid: iceberg lettuce (mostly water, low nutrition), citrus, onions, garlic, avocado.
Why bread is wrong (the short version)
Bread is calorie-empty and fills ducks up without giving them the protein, fat or micronutrients they need. The consequences:
- “Angel wing” deformity in young ducks. Bread-rich diets while wings are still developing cause the last wing joint to twist outward. The bird never flies properly.
- Algal blooms at feeding sites. Uneaten bread rots in shallow water and feeds blue-green algae, which kills fish and can sicken the ducks.
- Aggressive behaviour. A pond used to bread becomes a competitive zone - dominant males drive other birds off, ducklings get pushed away, the whole social structure goes wrong.
- Disease transmission. Bread crumbs concentrate ducks at the bank where avian flu, botulism and aspergillosis spread faster.
The full case is in can geese eat bread and can swans eat bread. The short version: don’t.
How much to bring
A small bag - 100 to 200 grams - is plenty for one pondside visit. The temptation is to keep feeding while the birds are interested, but that’s where the harm starts:
- Overfeeding teaches habituation. Ducks that get fed daily lose their fear of humans and stop foraging naturally.
- Year-round feeding suppresses migration in some species. Mallards and Canada Geese populations have grown in urban parks partly because they don’t need to leave.
- Concentrated feeding spreads disease. A clean pond stays clean; a heavily fed pond doesn’t.
If a pond has obviously well-fed, year-round resident ducks, the kind thing is often to walk past without feeding at all. They’re not hungry; they’re conditioned.
The bag we keep in the car
A 50 lb sack of cracked corn keeps for months in a sealed bin and turns one car-boot bag into a season’s worth of pond visits.
CountryMax Cracked Corn 50 lb
The pondside food that doesn't get you in trouble.
A 50 lb sack of cracked corn, the same product sold for poultry. Cheap per kg, stable in a sealed bin, fast-eaten at the pond so nothing sits and rots. Decant into smaller bags for individual visits. Replaces every single supermarket "duck food" we've ever tried, none of which actually work.
- 50 lb sack - a season's pondside food for one visitor
- Cracked to the right size for ducks and geese
- Decant into resealable 500 g bags for each visit
- Store in a sealed metal bin to keep rats and pantry moths out

Foods you might be tempted by but shouldn't bring
- Bread, crackers, popcorn, chips, biscuits. The full case is at what to feed wild ducks.
- Rice. The wedding myth said cooked rice harms ducks. It doesn’t (see can ducks eat rice) but it’s also not nutritionally useful; skip in favour of corn.
- Cooked meat, scraps, dog food. Some myths say these are fine; they’re not. Ducks aren’t carnivores in the way we are.
- Anything sugary. Cake, doughnuts, sweet biscuits - they’ll eat it but it’s harmful and habituating.
- Mouldy food of any kind. Aspergillosis kills more pond waterfowl than people realise. Mouldy bread is doubly bad.
For backyard pet ducks - different rules
If you keep your own ducks rather than feeding wild ones, the diet is different: a formulated waterfowl feed as the base, plus the same supplementary foods (cracked corn, greens, peas, mealworms) as treats. See are ducks a good pet for the full husbandry layout.
For wild ducks specifically, the broader question of what to feed at a pond is at what can I feed ducks at the pond.
The bottom line
Cracked corn, thawed peas, plain oats, chopped greens - in 100-200 g visits, not daily, not in bin-bag quantities. That’s the whole feeding-the-ducks-at-the-park problem solved. Bread genuinely harms them, even though they’ll eat it. The pond they live on stays cleaner, the birds stay healthier, and the next generation of ducklings has wings that work.
