So I bought on second hand to turn in to a coop. http://www.keter.com/products/manor-46s/ its this one. Now I have noticed the walls are thin but we don't have the severe winters. Mostly around - 15 C in winter times. I need some ideas about roosting and nest boxing. At first a was thinking no drilling in the wall so I need to make some kind of ladder roosting and nest boxes on the floor. But I also want some storage room for food and things and was thinking to use the upper space for nesting boxes. Wood is very expensive over here but would I need a board against the walls so I can secure things or not? Any advice is welcome this is my own project and I am not a handy woman but still want to try it.
