We found 4 baby Eastern Box Turtles in our front garden about a month ago. It is the beginning of winter here and we have a terrarium with heat lamp and UVB light per our local pet store recommendation. But they still seem very lethargic, sleeping most of the day. Is that normal? They keep trying to wipe something off the front of their face or beak with their paws but I don't see anything. Do they have a reaction or is this normal? They seem to like meal worms but only 2 out of the 4 are eating. Is that normal? What else should I be feeding them? What are signs of illness or other common threats? Thank you in advance!
