Hi all, Firstly, what a wonderful, friendly website and what a wealth of fabulous information! I am a chook newbie and I am in the process of building a coop and run for 4 Black Australorp hens (yet to be bought). I have made most of the plans up on the hoof as the design brief was "don't spend any money" so it had to be made of whatever off-cuts were in my shed. So far it's going well. My question is regarding the roosts; I plan to have 2 of them at about 2.5 ft and 4 ft off the floor. I see from other posts that appx. 10 linear inches per bird is the go, but how much space needs to be around them, ie how far from the ceiling and how far away from the walls. Thanks in advance, I'm sure this will be the first of many posts!
