I hear a lot of you talking about peeking problems. In the wild the chicks are in the dark at night and bright light during the day. Would a black light at night and bright light during the day work? Would it harm the chicks? I will have them in a brooder under a skylight in my bathtub. So they will get natural light during the day and the other for heat. Mine are suppose to come any day now. I'mm waiting impatiently. Jean
