Why ever did you use them then? If you really want to be organic, surely your own compost heap is all you should need.
I do not bother with using buzz words and going along with fads. If the crops taste good and I do not have any issues with the fertilisers/pesticides/herbicides I use, I am happy. It must take the fun out of gardening if you have to question every action you take.
Growing your own is healthy enough for me. As for chicken sh!t. I used to let mine run over spare bits of ground. Their droppings would be everywhere and dug in after. I don't know what was in the meal I gave them, There could have been all sorts of additives. But hey, I'm still here.
