I am new to chickens and I have I think winterized as much as I can according to all the great help I have received from this site however I need to know what to do when it is very cold snowing with wind. Should they be allowed out into the main pen or should I leave them closed in there 4 x 4 x4 coop. I have a secures area that I keep for the run during the day when I am at work but when I get home I let them out in a huge pen area covered with bales of straw. I heard they do not like snow so I planned on throwing straw out on top of snow to help. I could really use some advise.
