Is that a extension cord ? that should be replaced with a heavy duty one if it over heats it will fail .
I wrapped my heating pad cord with electrical tape also ( I use it under the dishes to keep the fermented feed from freezing )
tell me more about the cave & . -..Is it only warm on top ...not under ?
The fact that they are on top ...indicates that is where the heat is .they may be a little cold
heat lamp - what is this like ? where is it ?
They are the leading cause of fires in coops
heres a story ...that is somewhat comical

If in Doubt of their safety..
Bring Them in ...a couple days cant hurt ...I personally would ..I would sleep better knowing they are safe & warm ..
as they are little ..if they were bigger I wouldnt worry
