Can you feed the ducks

I don't know about the vending machines, but ducks and geese love frozen mixed veggies. I believe they like seeds also.

Yes, but there are signs posted asking that the ducks and geese not be given bread, since bread is not a normal part of their diet. I'm not familiar with what ducks and geese should be fed so that should be googled and planned before you go. I don't recall seeing "duck food" vending machines in the park... Someone please correct me if I've missed food dispensers.

Yes
