I have a lot of chicken poo mixed with pine shavings and hay. Maybe some seeds from their scratch grain. I have a hole in my yard where my son was going to build a garden about 8 years ago but my husband never bought him the soil for it and he lost interest. So, I have the poo, what else do I need? BTW, we don't drink coffee and don't know anyone who does. Oh, yes, I have dogs, can their poo go in there too?
