I don't have pictures of the process but it's pretty easy to explain and understand, I think. So, here goes...
The structure which the blue one is under is his "Mama"
I took an empty apple cider container and put about an inch of water in it for weight, turned it on its side, wrapped a heating pad around it and put some fabric over that and safety-pinned it all in place. Then I just had to find something to put under it so it would be off the floor of their little box about an inch and a half. The heating pad is on low and it keeps them toasty warm underneath it and I don't have to have the light on 24/7. Pretty cool hu? I have some little snippets of grass from one of my fodder trays in there for them to pick at when they decide to try eating.
I have "s" hooks hooked though the safety pins at the top and hooked onto the edge of their box so that it cannot fall over.
