also, other than fire, be careful for moisture, heat lights can and will explode if they get wet, make that lil loop(dunno what its called), but u loop the cord so water cant run down it towards the light if it rains outside. most of my chickens do just fine outside with no supplemental heat, and the only ones i worry about are my silkies, although they sleep in a pile in the winter. Something i havent tried, but will this winter, is a ceramic heat emitter, they are at most reptile supply stores, they screw into a light bulb socket and put off heat but no light, they are much more expensive, but are not glass.
