if you compost or have read up on it, chicken poop is a green when it comes to your pile. I dont make anything elaborate....Actually recently my 2.5yr old helped me expand our composting area. I found a fairly level area (I live in mountains, so I am limited) dug a small trench outlining my area and then filled with 6'sections of logs and staked in with some metal bars to hold them in place. i throw old my kitchen scraps (no meat or oils) and the chickens poop and old bedding, small sticks (i break into little pieces - large sticks save for a hugelkultur garden) I mix mine every 2-3weeks and let my little one go out there with his little shovel and stir it up anytime he wants. honestly there is no better garden soil supplement then composted leafs with composted chicken poop! Now for the best fertilizer in the world...I will let you in secret that has been shunned since the black plague, not for it's danger, but the education of the general population.....Per 1 gallon of non-chlorinated water, mix 4 cups of Wood Ash-(organic-no cigarette butts or ink or fuel. etc...) with 1 - first morning pee (do not use urine if taking medications!) and this will work better then anyother fertilizer and is sterile and safe! - In addition you can, throughout day urinate around garden and yard! Don't waste a free resource clean resource! If you do not spread it around, it can create a bad smell, this is easily corrected with a small amount of Dolomite Lime sprinkled around. The only reason this is not a common place in agriculture, is that 90% of N based fertilizers use N harvested from the petroleum industry...If we switched to urine for our agricultural needs we would "literally" piss a billion dollar industry away!
