Just look

Chicken-heat-lamp-amps, a heat lamp suspended above the brooder is what many people use. it's inexpensive and it works - to some extent. an infra-red bulb is the more efficient than white, as it doesn't stop the chicks from sleeping, which white light does, and can help prevent pecking. alternatively a lamp like this gives off no light at all.. Heat lamp reflectors, ordinarily made of aluminum, commonly include a hanger and a clamp. the problem with the design is that there are several points at which its parts can fail. i never use heat lamps and strongly recommend chicken keepers never use them either. the heat lamp clamp is easily knocked free from whatever it is attached to.
