I am free ranging my chickens, but already thinking ahead to wintertime. My current question is (of about a hundred at this point so bear with me, lol!) do I need a run to give them outdoor shelter during the bad weather? If I'm free ranging them, could I just build some kind of shelter for them to go to and then skip the chicken wire fencing? Hope that this isn't a stupid question, I was searching the posts, but couldn't find this particular question.
