Should you keep your chicks chicken heat lamp on all the time?

Yes, because if you turn it off you might kill the chicks and I am not sure but this is what I think. Day old chicks need to have a maintained heat of 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.
