I have been researching forums on different styles of light bulbs for coops. One forum said use a red light bulb. Other places have mentioned a low wattage CFL bulb. Is white light inside a coop ok for my chickens? It would be on a timer to come on only in the mornings to give them 14 hours of light. Still new to chickens as our neighbor moved 2 weeks ago and gave us 5 very friendly chickens and coop! Thank you in advance.
