Hullo, well it seems winter is really here. With temperatures down into the single digits and maybe negatives at night and teens/singles in the day, I was wondering if I should still open the door and let them free range. I let them free range all day. If I don't open the door to let them out, it will keep it warmer and less wind in the coop. However I don't want the chickens getting bored and aggressive and maybe feather picking. They don't seem to like to go outside especially with the cold and snow. So should I keep them inside and warm, but possible aggression or open the door and let them get colder? They seem to like to sit in the door way and look out even if they don't go out. One more thing, my coop floor is 4'x4' but there is roost space. This may seem small but they go outside for most of the day on nice days and only go in to sleep and get out of wind/snow/rain ect. Any help is greatly appreciated. Thanks!
