It's also possible that she has something else going on with her stomach...I hope not, but what you describe is way off the beam for normal stool...you might want
to get the next FRESH sample checked A.S.A.P. by a vet, especially if it too seems odd. Her temperatures should be fine for digestion, so something else is off, IMO.
And watch closely...sometimes a sick snake WILL go right back into another shed...if she does, that also will tell you something. (<vet time)
