Our rooster decided he didn't like living in a coop. He moved into a large hedge. He comes out in the morning and goes in at night. My concern is the cold weather will he go inside if it gets too cold or just stay there. During the day our hens 9 and the rooster just free range in the back yard...

We've done a few around here. wind blocks, straw on the ground to keep moisture down. Food at all times to help them keep warm... Other ideas???
