I keep reading that chickens are supposed to sleep on roosts. But nobody has ever told my chickens that, and as a result, they prefer to sleep in one large pile at night. They have prefered that since the night we got them home from the feed store, at just two days old. Not only do they like to sleep in a pile, but for some odd reason, they always sleep right there at the door to their chicken coop. Five chickens are currently sharing a chicken "hotel" that is 13 feet by 7 1/2 feet by 6 feet tall, and they all pile up at the door, thus blocking me from being able to come in at night. Is there any way to teach these birds to sleep on their roosts? Or at least to move their collective little carcasses to another corner of their coop?
