A heat suspended above the brooder is what many people use. It works to some extent. An infra-red bulb is more efficient than white, as it doesn’t stop the chicks from sleeping, which white does, and can help prevent pecking. Allow baby/birds/animal space to move away from the lamp. If chicks huddle close together for warmth then lower the lamp an inch or two, you can use at least two bulb per brooder, if one burns out in the wee hours of the light, the other will keep the chicks warm until morning, but be very cautious about keep anything flammable away from hot bulbs. And when you put your chicks inside brooder you can wait until they‘re at least four weeks old before you introduce them to the outside world and only then if the weather where you are is warm. By four weeks they will have some feathers, which are their main way of keeping warm. Heat lamp can be kept on all the time without any problem.
