How old are your ducklings? they can be in water right off you just never leave them alone and after they come out you make sure they are put right back under the heat lamp to dry, so they don't chill. water temp should be around 85-88* just start with enough water to top of their legs then as they get use to it add a little more till they are floating next thing you know they will be diving under water and having a blast[have your camera ready] do this gradual deepening of the water over a couple days .Ducklings without a mama don't have water proofing right off but by putting them into water it gets them started preening and gets the oil gland working so when they get older they will be able to get that oil all over their feathers. and then they will be water proof. .
