runny poo, advice?

[Athena&beepbeep'smom]

Okay, Athena for the last two days has had very runny stools. There's no smell. The solid part still has the same look and texture. It's just that the watery part is very extremely watery. She does not appear abnormally lethargic (it's winter so she's going to sleep earlier but has been for two months). When she's awake she's playful and alert. still using all of the cage. still eating and drinking normally etc. Of course I know the right and best answer is to take her to the vet, and I do have an excellent avian and exotics vet. But the one and only time I brought Ms. Athena to the vet she freaked out, pulled a blood feather, and didn't act or eat right for a week, so I just thought I'd check here first and see if anyone had any tips or anything I could rule out before taking the plunge at the vet.
