Another good hint to know if they are in shed, specially when young, is the way they place the head in the coil.
A good number of neonate-to-yearlings GTP´s (and even some adults) place the head sideways in the coil when coiled (in a goofy way). As Miguel mentioned, their heads swollen and it becomes a bit unconfortable for them, so this is a way to try to avoid such uncomfort.
Another thing I´d like to point out referres to your first post and the feeding atempts.
You said that in mere 2 weeks you tried "live, frozen, leaving in cage over-night, braining, and chicken broth".
How were you able to try all of that in 2 weeks? You offered food every other day?
If so, I would recommend against it. Even if she was off food, insisting that much would only aggravate the issue because it stresses GTP´s a lot. By doing that even if there is no "off food problem", you may start one.
Offer on the same week day. If she eats, great; if she doesn´t wait one week and offer again.
Neonates can be 8+ weeks without food without problems; yearlings to sub-adults several months; adults can be a year+ without food.
Adult males usually fast 6-7 months per year.
They´re prepared to that. So as long as they are hydrated, don´t worry.
