Yeah, a 3 sides shelter. I'm just curious if that was a design choice or if the birds had a reason they didn't have a 4th wall with a smaller doorway to seperate the inside pen from the runWhat do you mean? " the inside isn't separated from the outside by a wall"?
Each pen is separated by wire and the sheltered part is separated with plywood walls, so the sheltered part is 3-sided plywood walls.
