No. Plain water is fine. Did you get these chicks in the mail? If so, and they had a long journey or seem sort of listless you can put a little sugar in their water to perk them up, but only do that the first day you have them. After that, they're fine.
I read on Murry McMurry Hatchery when I ordered my chicks that there is something you can add to the water, and I can't think of the name of it now, but when I did go to buy it at TSC and Rural King, they did not offer it. so I never could find anything. I hear that 1 tsp to 1 quart waterer on the first day is okay if they are shipped. but I'm not chicken expert. I think that Mcmurry also mentioned something about that also. Might check into their site and see what it says.
