Good morning, I am the proud owner of a 4 year old female spur thigh tortoise. I have had her around a year and a half. Her weight today comes up as being low weight for hybernation on the jackson scale. I have researched a lot on winding down etc but cant find when the jackson scale should be used? Is right before starting hybernation process too late or ok? She is on a tortoise table with lamps etc currently.Any help is very appreciated as I have a lot to learn!! Holly x
