I was very pleased to see that proper breed selection was the first item on the list; it certainly belongs there! Choosing a good breed for your climate, weather, and available habitat should be the first thing any chicken keeper considers--but often isn't. I would have liked to see more mention, if not discussion, of using greenhouses for winter runs/free-ranging. The whole function of greenhouses is to create a warmer, sheltered microclimate, perfect for helping poultry get out and about during the the harshest frigid coldsnaps. Many agriculturally-inclined people with any amount of land in cold regions already have greenhouse space for winter crops and composting that could be adapted for parttime or shared use by chickens with minimal additional trouble or expense. I believe Harvey Ussery has written about this some in his book and on his website, themodernhomestead.us.
