Rural Gardening: Help! Baby geese or ducks?!, 1 by DrDoolotz

Soooo, after Kelly delivered the Animal Rescue League's borrowed trailer (from getting the donkeys, which I will post about later), he came home. With 11 web-footed creatures. I think they are ducks, but the ARL said they might also be geese.

I know absolutely nothing about ducks or geese. There are 4 large-ish white-ish colored ones. There are 4 much smaller yellow-ish colored ones. there are two black ones with white splotches, and one grey-black-ish one with a stripe on its head. They all have these really cute but pathetically tiny wings. There is no way they can flap out of the tank. A 3 week old chick has more wings than these guys!

They are in a 2 foot high aluminum round tank in our basement. I put paper down and gave them chick starter and water.

Does anyone know what they are?
Does anyone know what age they might be from looking at them?
Does anyone know how often I have to play with them in the tub?
Does anyone have advice of any sort?

Please?
