Charcoal is a must in every pigeon and chicken coop. Pigeons and chickens love it and it is very beneficial. Wood charcoal will reduce the effects of diarrhea, prevent and treat Coccidiosis and reduce the odor from droppings. Wood charcoal, when mixed with the droppings will make a better fertilizer. Other benefits include better health, reduction of toxins (poisons), and stronger egg shells. Mix with your grit or place in a small container for the birds to eat at will. Granulated Charcoal 3 lbs.
