I need to ask if the way I am handling my chicken droppings is appropriate. I have 3 hens and I clean out their coop about once every two weeks. I take the droppings and wood shavings (About 50 / 50 ) and place them at the bottom of my fruit trees. I have been doing this for about 4 months. I can see no damage to my trees (Avocado, Apple and Nectarine) Does anyone know if I am damaging my trees?
