Your ducks are lovely and I'm glad they are not discriminating against the chickens.
My mum always said its not good to throw food away. So what you're doing is really cool, because it's kinda like recycling. ( part of the advantages of having animals around)
They must really love that noodles, they seemed real happy to eat it.
And yes they are looking fine, so excellent job sir for taking care of them.
It is a great way to recycle!
