When you say force feeding what exactly do you mean? What is the technique that you're using to "force feed" and was this recommended by the vet? How long have you been force feeding her? What are you using for heat and how are you measuring your temps and humidity? What are the "steady" temps and humidity at right now? Has the vet told you what the scale issue is? Pictures of the scales would also probably help or explain what you're seeing. Sorry for all the questions but right now trying to pinpoint the problem is like taking a shot in the dark.
