Puddles I'm sure must be more tasty! Mine always like puddles better than water dishes also.I'm hoping Duncan just got up for a drink. No, I don't wake them to soak but I have been soaking the one that hasn't hibernated yet. This morning he was drinking from his dish, which was filled with rain water. They all prefer to drink from puddles if they have the option. Plenty of puddles now!
My reptile vet has always told me to soak desert tortoises once a month, even ones hibernated outside in burrows. The two who were hibernating may have just gotten up for water. Research has shown that desert tortoises in the wild get up in the winter to drink water and then go back and hibernation. In the wild it's usually once or twice during winter, but their burrows are very deep – as much as 20 feet so they hold in the humidity better than anything we can build for them.
Hercules is still up, though. Has he been eating? It is pretty late to still be awake.
