btw i found it works very well as white noise
We used to feed the ducks at the lake in the park.
We bought poultry food at the local tack and feed store.
There were dozens of them. When they got spooked and all started flying, the breeze was notable.
Park eventually put in a sign to stop feeding them and took out the benches.
- Bread doesn't have much nutritional value (especially the kind of white "bread" that is common in the US for example)
- It fills up their stomach fast so they don't forage for foods they would naturally eat
- Throwing bread at one place can lead to overcrowding (which is what happened in your great fishing spot) which stresses the animals
- They also shit a lot in one place, which leads to a bunch of problems
- Uneaten bread causes algae growth which leads to diseases and pests
best to feed them peas like in this neat app or I also heard that cut up frozen grapes are a good choice.
