Hi Jeff, I don't think that any of them are molting. They were hatched out late June of this year, I don't see a bunch of feathers around, and the weather has been pretty good (San Diego, CA) except for the time change. And I've addressed that by adding supplimental light until 8PM, but they still head off to bed around 4:45 PM. I do monitor what they eat, they have an unlimited supply of laying crumbles, giving them mixed grains and homemade plain yogurt and veggies/fruits. I know that there are various opinions on using light, but does this tie in with the molting process? Is it neccessary to the health and welfare of the hens, or does it depend on region/breeds? I know studies have been done on humans and light, and how if they are having physical/emotional/mental issues during winter, by adding simulated natural light, this counters and balances their systems. I know that for me, I NEED light. Come to think of it, everybody whom I know is a natural morning person is the same way.
