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 is quite common in pigeons, and if you suspect your birds may have it, you may want to send in a sample of the droppings to Foys. We partner with a veterinarian who will look at the droppings thru a microscope and will know right away if Coccidiosis is present. He will also be able to tell you if worms are present. The way to send the droppings is listed elsewhere in Foys catalog. 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.
