I haven't had a chance to navigate through the site yet to see if these questions have been answered. I've been contemplating building a coop and raising a few chickens for a couple months now. Not sure if I've lot my mind or what but, here are a couple questions regarding building a habitat that works for our lifestyle while providing a nice little egg making sanctuary for the chickens. Is there any concern with having the coop primarily in the shade during the winter months when the temp can drop below zero? Do retractable fences actually work? What is the shortest ideal height for sectioning off a area in the yard? What are the best egg Laying cold hardy breeds? (our summers get pretty hot) Any random tips, do's & don't or advise is greatly appreciated? Thanks! Hopefully this will turn out to be everything I hope it could be!
