Reward treats with 2 kids

It might be a bit hard for D4 to sit and not throw bread and there might be major tantrums and ruin the whole outing in the process.
Maybe let it go this time, have fun feeding ducks and then at the next "bribing" (which all of us do ) make it something that can be only for 1 child. Eg gets to sit in the front seat or while the other is occupied you could do drawing together or something special that they like.
Gosh i didnt realise how hard its going to be until i had to think about it just then!
Sorry im not much help, ive just confused myself!
Let us know how it goes

Personally I would take them both out, but only let the one who behaved feed the ducks. In my opinion, you need to stick to your guns as I would imagine it will only make things harder in the long run - she'll get the idea that even if she is naughty she'll still get to have the treats.
