An indication that chicks are comfortable in a brooder is that they spread themselves uniformly under the hover. Chicks need warmth to survive, especially during the first few weeks of their lives. A brooder provides warmth through a heat source, usually a heat lamp or hover. Chicks that are too cold will huddle together under the hover to conserve heat, while chicks that are too warm will move away from the source of heat or pant and sit with their mouths open. However, when chicks are comfortable in the brooder, they will spread themselves uniformly under the hover. This indicates that the heat is evenly distributed and that the chicks are not too cold or too hot. When chicks are comfortable, they will also be active and alert, eating and drinking regularly, and moving around the brooder freely. Therefore, spreading themselves uniformly under the hover is a good indication that the chicks are comfortable and healthy in their brooder.
