I don't use any light either and my few young ones (under a yr) still lay every day. The rest are pullets(24wks) and waiting still for them to lay, so I don't think I'll have to deal w/molting till next yr. My ducks are only 8mos old and they are still laying every day also, I'm thinking age has alot to do with it. Slow down when they get older, kinda like us. lol
