Good morning, I have a 4 year old female spur thigh who I have owned for about a year and a half. I was planning on hibernating this year. When I weighed her yesterday she came out as low weight for hibernation on the Jackson ratio scale. Not sure when this should be used? right before hibernation process?? She is currently inside on a tortoise table with lamps etc. Not sure if I should over winter her this year. Any help appreciated as still a new owner learning.

Thank you
