1qt Bird charcoal For Small Birds - Activated charcoal granular - Health, healthy, canaries, parakeets, love birds and finches, cages BIRD CHARCOAL (SMALL) For canaries, parakeets, love birds and finches TESTIMONY: Gary raises racing pigeons, about 150 of them. That bird charcoal (LARGE) really works. I mix a ratio of 1 scoop of charcoal to 5 scoops of regular grit and just have it there for them every day. Ive noticed that their general health is better  better droppings and better feather quality. Ill be telling all my pigeon friends. Gary, Texas
