A really effective product for treatment or Coccidiosis. Prevention is always the best, as in any disease, and the best thing you could do is to be sure your loft floor is dry. Many fancy breeds spend a lot of time on the floor, breeds such as Fantails, Muffed Breeds, Runts, Kings, etc. These breeds are more susceptible to Coccidiosis because if the floor is damp this creates the ideal breeding ground for Coccidiosis. The powder is 1 tsp/gal. The liquid , which is 9.6% is used at the rate of 2 teaspoons to a gallon and used for a suggested 7 days. The powder, which is 20%, is used at the rate of one teaspoon per gallon and also used for a suggested 7 days. Coccidiosis is not a disease it is a protozoa or similar to a very small bug, and usually has droppings of very light green which may include small amounts of blood. Coccidiosis will develop resistance to any drug very quickly and it is a good idea to rotate Corid with another drug such as #2508 Cox/Trimethroprim. Do not combine with anything else and change the treated water daily. THIS PRODUCT MAY NOT BE SOLD OR SHIPPED TO CALIFORNIA Corid 20% Powder (Amprol) 10oz.
