Very good information here but I still have a few questions.
The chicks stayed in the dining room for the first week. They moved out to a heated shed (60F) for the second week. I used the heat lamp for the first few days and then turned it off for longer periods. They live at 60F and seem not to mind it always running and doing fun chick stuff until they are tired.
Last night I turned off the heat lamp and lights at 10pm and today at 6am I turned on the room light and they all ran for food and water. BTW it was pleasant last night, it only went down to 30F last night outside.
#1 is that too long to go without food?
#2 Is 60F warm enough without a heat lamp?
They will be starting their 3rd week tomorrow.
