Hi everyone. My mother lives in Tucson and has 3 old desert tortoises and I wonder if they will be ok if they bromate in a burrow all winter. In the past my dad would put them in banker boxes with dirt, ripped newspapers, etc and then stack them in a dark corner of their back patio and they were fine until spring. My father passed away 2 yrs ago and last year I was able to catch them and get them into their boxes. This year 1 of them made its way to where the boxes were usually stored and has gone into hibernation so, my mother boxed that one. The other 2 are no longer leaving the burrow. Will they be ok if they spend the winter in a burrow or should we get them out? They are close to 30 years old.
