We've had pretty mild temperatures for over a week now, 12c yesterday and 14c forecast today but much warmer in the greenhouse of course if the sun is out. I had a look a while back in the tub of soil and they have moved from the spots where they buried down originally. I can see the top of the shell of one of them but I'm letting them just come out themselves. With the insulation round the tub of soil, any change in temps is very gradual so although it can get very warm in the greenhouse there's not much of a change in the tub.
The fact the they move around in there during hibernation would always make me wary about the fridge method. Do they need to move around to keep their joints from seizing up or what?
