Use chick behaviour as the final guide — panting and spreading wings means too hot; huddling and shivering means too cold.

Reading the chick is more reliable than reading the thermometer
Setpoint values are starting guides. The chick's behaviour is the ground truth. A comfortable chick lies relaxed, breathes evenly, and explores. A panting chick with wings slightly out is overheated. A chick huddled tight against siblings or against the heat source is cold and burning fat reserves.
Use a probe thermometer at chick level, not at the brooder lid. Heat rises and the value you read at the top can be 3–5°F higher than where the chick actually sits. A second digital hygrometer at the same level gives you a real read on humidity, which matters more than most breeders realise.
Power outages are the silent chick-killer. A small UPS rated for 30 minutes plus a battery-powered backup heat source (warm rice sock, thermal blanket) buys enough time to move chicks somewhere warm if the brooder fails.
