Hi recently purchased a 4-5 year old female amel corn snake.
I'm wondering if she might be overweight, I haven't had an adult before so I'm unsure if this is normal or if she is on the heavy side.
I question her weight only because there is some skin showing through the scales on the back half of her body, and it's pretty even from the middle of her, back to her tail.
She was fed by the previous owner three days ago, and she was brumated last winter I believe? But has not been bred, and the previous owner did not mention anything about her having laid any eggs.

If she is simply heavy, what should I do as far as feeding and exercising?
Also if she is gravid, would a 2 year old male be too young/small to introduce to her?

I will try to add a couple photos shortly.

Thank you!
