I would dig it up and soak it daily. This time of year, many of them just want to sleep. Warm soaks usually wake them up and stimulate appetite too.Thank you Tom for replying! I will make sure it does not go below 70F.
Also, I've seen the baby sleeping a lot. Is it normal for a baby Hermanns to sleep 12 hours straight in the hide under the bedding (it burrows under the substrate to sleep at night) and during the day, after eating, it sleeps under the basking light. As I am typing right now, it is laying down and sleeping... I am thinking, just like human baby, tortoise baby should sleep a lot, but I am not sure if that is normal. I had to wake the baby up in the morning for soaking in the water, or I feel that it can continue to sleep under the substrate. Should I wake it up? or just let it sleep.
If your tortoise is basking a lot, you might want to warm up the day time ambient temps a bit. It can still get cool at night, but warmer ambient temps during the day might discourage the excessive basking. You can use your thermostat and a timer with your CHE for this. Set the CHE on a thermostat to 80-ish, and plus the thermostat into an appliance timer. Set the daytime heat to come on a couple of hours after the basking lamps, and go off a couple hours before the basking lamps. This will simulate the cooler morning and evenings outside while still giving your baby lots of daytime warmth. Adjust as needed depending on behavior. This will also tend to dry things out in an opened topped enclosure, so be mindful of the dryness and add moisture as needed.
