Hammies don't drink a lot anyway so it can be hard to tell sometimes, I'm sure she'll figure out her bowl for a couple of days. She's probably just being a bit shy while she settles into her new home. You can make an impromptu water bottle stand while you're waiting if you're worried though. You can chop the top of a plastic bottle and a hole for the spout & put the bottle in that, just weight it down with something. Or give her a slice of cucumber for some extra moisture
