I have a 4x8 chicken coup thats fairly tall. I put a 1" branch as the roost that comes out from the wall about 6 inches. I have a ramp that leads up to this roost. Right now I have 3 2month of chickens that appear to use it, it seems it takes them quite a bit of time at first to get situated on it. What is the recommendation for how far the roost be from a wall and how high it should be? I am going to add some more chickens to the coop and was thinking of adding another roost higher up. anybody have plans for a ladder type roost?
