in light of the insanely high gas costs, i'll be wanting to keep the heat down at home while i'm at work - BUT - i don't want to come home to birdsicles. so what can i use? is there a specific product i can attach to the outside of the cage? or can i just run off to home depot and buy one of those aluminum-looking lamps with the clamp on them? i see breeders at shows all the time with heat sources, and that's what they look like, and the little buggers look adorable - like they're sitting in front of a roaring fire. but i don't want to assume it will work and it either doesn't, or it cooks them. any suggestions?
