I was wondering if there is any common wisdom regarding the color temp of the light one uses for increasing the daylight hours during the winter. Is a "daylight" light bulb better than a regular soft white bulb? Any color tints more effective? Also, for a small coop (4x8' floor), how many watts is needed to effect the hens and "trick" them into laying again? Along the same lines, I am also using a heat lamp to warm the coop during really cold outside temps ( below 10F). I ended up with a clear heat bulb, but there are also red colored ones available. Since this heat bulb is on quite a bit during cold spells, I was wondering if having a white heat light on 24 hours a day will impact the hen's day/night cycle, and if a red bulb would be any better?
