when I used to hatch out ducks and chicks, I used to use what is called welder's wire, or rabbit fence, covered in newspaper. this way, their little toes don't get stuck in the wire, and yet if they spill thier water, it goes on through so they don't start to stink.
Once they got bigger, I just used the wire. I have also just used the paper. As far as spending the money on bedding, you can if you want to, but they are just going to poop in it and get it wet from water, trust me ducks are VERY messy when it comes to water, especially the babies.
Good luck, I wish I had some baby ducks again, I have two ducks, both girls.

You need to provide something with lots of traction, such as shaving or wire--no newspaper, it's too slick and can cause problems such as Spraddle Leg. The wire is a great solution if you have an old rabbit hutch or bird cage it works great. :) Shavings are good but you'll be changing them often.

See this 'safe/unsafe plants list for more info:

I see that oak is on the 'toxic' list, while aspen isn't on either list--but I know pet shops sell aspen shavings. Please note what it says at the top of that page that pressure-treated lumber contains arsenic!
