Chirping
I like to watch the behavior of my baby chicks to determine if they are too hot or too cold. If they are pressed against the edge of the brooder trying to get away from the heat lamp, they're too hot and it needs to be raised up. If they're cheeping very loudly and huddling together under the heat source then they're too cold, and it needs to be lowered. I personally prefer this method over a thermometer.
