ok, since i have 120 eggs going on between now and the middle of october... (most my friend is hatching out since my incubator and i hate each other) i am trying to build a 3 tier brooder. basically, it is 6 feet high (ok, so my family is all tall) and each brooder is 2 feet across, by 1 1/2 feet high and wide with a wire front and plywood sides. My question is....if i use red heat lamps on one side...do they get really hot (like to the touch)? dont want to burn the birds. or do i just use a light bulb and put a wire cage somehow around it???
