We currently have a 1 x 3 board for the girls' roost. They don't seem to have any problems getting on and off it. But some of our friends and family (who have experience with raising chickens) look at us and ask us where the roost is. They are incredulous that we use the board, saying they need something to "grasp" so they keep their balance. I have read on here that people use 2 x 4s with the 4 inch side at the horizontal so that's what we did. Now I'm wondering if we need to change this or add an additional roost, using maybe an old tree branch or something. Even at that I'm not sure how big it should be. So do I need to change this roost or should what I have be OK? Don't want the girls to be uncomfortable. Thanks for any thoughts.
