How warm do chickens need to be lay eggs?

Chickens need to be kept warm enough to maintain their body temperature, which is around 105-107°F (40-42°C). If chickens get too cold, they will stop laying eggs. The ideal temperature range for egg production is between 65-75°F (18-24°C). In colder climates, chickens may need additional heat to maintain this temperature range, such as a heat lamp or brooder.
