Just wanting some opinions on what heat sources you people trust. My brooder box is going in a shed and it is still pretty cold outside. I have some 250 watt red bulbs from a local farm supply store left over from last year but 1/3 of those would randomly burn out. If that were to happen then my chicks would freeze in no time. So, is there a brand of bulb that people trust over the other? I have a few weeks before this batch is scheduled to arrive. Also, this shed has no windows. With a red light they will essentially be in eternal darkness. But with a white bulb the sun would never set. How do you deal with that?
