Everyone's advice here is pretty good ... I can't think of much to add except that you might want to try to make up a waterer that they can get their heads but NOT their bodies inside. They do need to be able to dip their beaks to clear their nostrils, and they HAVE to have water when they eat or they can choke. But ... if you have a whole brood of them and they are able to get in their water, ... well ... let's just say it will increase your housecleaning duties.
Besides, if they are so young, they don't know to get out of the water before they are chilled.
I did a couple of things, but they pretty much all involved a container of water with a small hole for the head to go in. I didn't try gallon milk jugs, but someone on here does and posted a pic, and that looks better than anything I came up with.
There are lots of good threads on here about just about any question you could ask, so if you need an answer quickly, you can search the archives while you wait for someone to answer.
Good luck with them, however it works out.
