Yes they would cook if enclosed. They are only covered - to protect
from birds & (?) cats - and well ventilated.

Garden soil I've previously sterilised before using for seedlings.
This year I got lazy. Could have been a problem; maybe not.

Still no new damage. I'm betting on a mouse (caught one last night.)
