I have a small suburban yard that I mulch areas of every spring to prevent weeds. I was going to go and buy mulch when I saw my just cleaned out pile of litter from my small coops (three chickens in one and two quail in the other). Can I lay the litter out as a mulch to prevent weeds? It isn't smelly or anything. The chickens COULD walk where I want to put it but they never do, they are afraid of the brick mow strip and never go off my grass. Would it grow asperilosis or something else bad for my chickens, or would it decay into the dirt? I am talking maybe two cubic feet of litter over 100 feet of dirt.
