I just permanently installed the roosting bar into my hen house. I wanted to leave space to add a second bar once my Marans get a bit bigger in case more space is needed. How far from the wall of the hen house should the roost be? Meaning, the bar is 8 inches from the front wall of the hen house. Is that enough depth? I guess the best test would be to see what they do tonight. I could have put it 18 inches or even a foot from the wall, but I thought I might add a second roost so I wanted the bar to be as close to the wall as possible.
