how long to leave heat lamp on chicks
Usually the heat lamp in a brooder box is used for the first two months. Chicks go into the brooder box within 24 hours of hatch and the temperature on day one is very close to the temperature of the incubator...95F. More on this   Day old chicks need to have a maintained heat of â¦ about 90 to 95F for the first week. A drop of 5 degrees F per week for the next three weeks is best. You will know when they do not need the extra heat as they will sleep/rest well away from the heat lamp as they get older.
