I have a heat lamp! I just hurd that if you put them alone they don't do as well b/c they don't have buddys to snuggle against. I will try the red heat lamp
. The bigger one seems to pick at both of the others but not real bad the only reason I was worried is b/c the one I broke out of the shell is sort of small and scrappy looking and I put him with them a little later so I thought they may not except him.
