I need some help in designing and laying out my roosting poles. For example how far away from the wall do they need to be? How far apart? How tall? I am enclosing a picture of how it is laid out so far...but I am not 100% happy with this? The dropping board with the PDZ is working great I just think the top rail is too close to the window? It's only about 8" away form the wall? Currently I have 7 hens and 1 rooster in here but 4 are chicks and not really roosting yet. The door opens in so I can only go out so far? The coop is 4 x 6
