Thank you for your responses, that’s all very interesting. So what I’m getting from this is, mostly, there’s no need to give much d3 for older torts that are outside all summer and hibernate. You mostly seem to just give it ( sparingly ) to hatchlings. So I think I will cut back on the d3, I do sprinkle limestone flour quite liberally on their food, most days, I don’t worry if I miss the occasional day.
Thanks all, that’s been most helpful.
