We have a compost pile that the chickens think is the greatest smorgasbord ever invented. Typically, I throw my spent coffee grounds from the percolator into the compost along with all the other scraps. Coffee grounds are a pretty optimal compost. Well, the grounds are interspersed with other yummies and I'm sure the chickens are ingesting some here and there. Question is: Is coffee good, bad, or neutral for chickens?
