I'm new to raising chickens and had a question about which breeds to order. If I live in a climate (I'm in Maryland) that can get down to the teens regularly in the winter and also into the 90's regularly in the summer, should I be looking for a cold-hardy or heat-hardy chicken? I assumed cold-hardy was more important because I will not be heating my coop but there will be plenty of shade and things I can provide for the hens to keep cool in summer. Would my assumptions be correct?
