Space can really help, but another thing you could do is add clutter. If you look, you will see that is a wide open space. A chicken is constantly in sight of all the other chickens. If you added some pallets, learned up against the side, little mini walls and some roosts, the birds will really like that too.
But the space was the important part, I am glad and I bet your birds are happy that you did it
