Yes, good article. Our girls have the run of the yard during the day; placed in the hutch at night. NO ARTIFICIAL LIGHT!! Still have access to the run below. I recycle the egg shells for calcium. I've discussed protocol elsewhere. I hang ears of corn for them to play "tether corn," which they like. Also homemade sourdough bread on occasion. Happy, healthy, good layers, and endlessly entertaining. My BP goes down when I spend time with our girls.
