Can chicken have water from the fridge?

It is really hot out there so I have been out checking on all my outdoor babies. Since it is so hot out can I give them water from a jug that I keep in the fridge? I just don't want them to get overheated.

I sometimes add Apple Cider Vinegar with Mothers is that enough of should I add other things to their water?
