Alright so, I thought that I had read somewhere that the lamp should be 18-24" from the floor of the brooder, however my heat lamp says that it MUST be 24" from combustibles. I'm assuming that pine shavings (and baby chicks for that matter) are combustible? As well, I used bleach to clean out the very large aquarium that we're using for a brooder because it's prior use was for turtles. I'm going to wipe it out with water several more times but what kinds of cleaner can I use in the future? Is bleach alright? So nervous...and excited!
