I have a quick question about night time lighting for chicks... My chicks are in a climate controled brooder with a coil heater. The only light in it is a flourescent bulb. I just got them yesterday and last night I turned off the light so it was dark in the brooder. I checked on them a couple times during the night and all of them were asleep and then this morning they were all up and about. They get natural light from the window. I guess I thought that a natural light cycle would be better for them, but should I leave the light on at night so they eat and drink during the dark hours?
