I wouldn't give her the propel it probably has nutri sweet or something in it. I might be worrying a little to much. As long as your little one is running around and playing like normal I wouldn't worry. She probably just ate something funky. I don't think I would give a baby chick drink made for people. If you are still worried tomorrow ask at the feed store if they have something like pedialyte for chicks. If it were me I wouldn't do anything and just keep an eye on her.
