I have read that there is a theory that chickens can be trained to roost where you want them to. My experience however, has been that once they are allowed out to roam for a while they will go for the highest nearby object they can find, and get on top of it. First 2 or 3 fly on top of the chicken house, then in a few nights the whole flock goes and lands on top of the coop. And the only thing that will get the back in the coop is me grabbing them and throwing them in.Very time consuming. Any suggestions?
