You posted to wrong post lolUh..not a good idea. The viruses that can come out of a birds butt can really damage people. The idea is to age bird poo, to degrade it even under heat, otherwise you have a raw sewage on a raw leaf situation for dinner, which is just gross and biologically dangerous.
Actually no. What I did wrong was I imagined for some reason that you were going to put an aviary screen over the raised bed garden. Why? I must have an over fertilized imagination is all I can tell you. I am sorry!
And yes it is plenty big for leaf production.
