Yes, I know that Silkies are not bred for their egg laying abilities....so maybe this does not apply, if so...let me know that too.. Upgraded coop and run and I have read that chickens need between 13-16 hours of sunlight a day to produce eggs. Coming into (fall) winter, we are running about 10 hours a day of daylight, in California where the winter average nighttime temperature will be about 42 and daytime about 53 and the daylight will be about 6 hours a day up to December and 4 hours a day through spring. So...I want to have lighting in the new coop to replace sunlight and would prefer to go LED, not using it to heat the coop, it is insulated... Question is, is there a wattage requirement to replace daylight? or is it a lumen thing? and what (degree) of lumen is needed to simulate daylight? and...does the color of the light matter? I now have an led rope light strung around the rafters...and the default color is "green"...which I have to switch over to "white"..... Does wattage, lumens or color matter to chickens? Or only if they have an advanced degree? haha Ideas?
