Ridgerunner-
I do not have artificial light, or heated water, no electricity to the coop. And while mine lost a few feathers, and for a while it seemed like there were feathers everywhere, none of them got bald spots, One does have a few feathers, in which all the edge came of the quill, she molted the hardest. The neighbor lady about 45 miles away, she does chickens serious, a couple hundred, and when hers molted they looked like they had some disease, with large bare spots. But maybe that is not real molt, but more feather picking? Cause she gave me a couple of those hens, when I got down to two hens left due to predators going into winter, and they were laying within a day or two of moving here.
my egg production went way down in December, and then January we have been have several very cold spells, well below zero, when it warms up, I get eggs, when the temp drops, I don't. I guess I am not sure if mine look rough due to coming out of a molt, or the very difficult weather we have been having?
