And again as I mentioned, we know nothing of the temps or humidity. And from my experience, when a snake is too cold, they tend to ball up and try to stay as warm as possible, not stretch out.
And as for hungry, not sure about your snakes but that's when all of mine are the most active.
And if a vet isn't an option for the OP, then a pet isn't an option either. What do you do if the snake gets sick? Let it sit there and die?
Sorry to be harsh but sometimes truth hurts and is harsh. My advice is surrender the animal to someone who can give it the care it needs and has the knowledge or has done the research BEFORE bringing said animal home. It's life is in your hands. If it dies, your life goes on but it's life doesn't. Anyways good luck.
