I keep a chicken scrap bowl in the kitchen and put all our scrap veggies and egg shells in it and feed it to our chickens every few days. I was wondering if they can eat coffee grinds. I haven't fed them any yet. I didn't know if I should or not. I heard someone say they use to feed there chickens coffee. it seems like it would be a decent grit but I don't know if I want my rooster up all night crowing. Lol. Any advice on coffee?
