Is there a typical type and wattage bulb for brooders? A friend lent me a 2' x 4' metal brooder with electical socket installed. There are no markings on the brooder as to what type watt/ bulb to use. I put a 100 watt and it smoked within seconds, tried a 60 watt and it seemed really hot. Keep in mind it hasnt been used in years so it could be burning dirt. Any clue what is standard? The bulb screws in and rests against a metal contraption that you can adust for heat control.. there is a thermometor that looks like it has seen better days I will put another thermometor in the brooder.
