So I'm expecting my chicks early next week, I've been testing the heat lamp, I have a 250watt red heat bulb (made by GE) and one of them UFO's.. I mean large silver heat lamp doodads that take these big 250watt bulbs... I know chicks need 90F to start off with, so I suspended the lamp and put a thermometer under it... it rose from 73F to.. 75F.. mm I lowered it till it was about 1+1/2 feet from the floor where the thermo was.. it rose to 80F.. How high above the chicks does the lamp need to be? I'm pretty sure my reflector is rated to take a MAX 300watt bulb so I'm good there. I just didn't expect to have to put the lamp so close..
