I walk by this business every few days, it's always full of people there. People are happy, in groups and alone, all doing this act of eating.. Not a single problem in sight.
This is a McDonald's restaurant.
Does that mean McDonald's is healthy and good for people?
(..maybe we humans need more signs... )
- 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.
The overcrowding can also allow bird flu to spread more easily.
I guess if you are serious about it you can spread it out and drop your peas in different areas and/or don't drop a huge amount at once.
