Want to use a heat lmp at nite. I have the reddish colored bulbs. Will use of these bulbs at nite affect the sleep of chickens?

Ronron, No, they seem to "sleep" pretty much by the actual outside daylight, even when they have regular incandescant lights extending their daylight hours. There are those who say it will affect them adversely (not the red, I believe), but I have always (for years and years) kept my chicks on 24/7 regular lights (for heat) for up to 3 months in winter time--absolutely no harm. I never use heat lamps, get better heat for the Wattage, and disbursed over the coop better with 100W clear bulbs with reflector hoods. Heat lamps heat only that which they touch directly. You can burn the head of a bird directly under, if too close, and others two or 3 feet to the side, will be cold. So use a thermometer to check if you are warming what you want warmed! Good luck, CJR

Ronron, What CJR has intimated is good advise, We have
a minimum of 1500 to 2000 in brooders at any one time.
The use of 100 watt clear bulbs with reflectors is
truly the best for all conditions. Not only ia it better for the chicks but better for you energy cost.

Use of the wafer thermometer can help to regulate your
over all situation. Good luck.Canary
