So a couple of my birds have bloody (raw hamburger type, but no other symptoms that I can tell) droppings. I think Coccidiosis. I rushed out and bought a 16oz bottle of Corid based on what I have read here. My questions are: 1) since the chicks (all about 5 months) and they are on a medicated grower feed, is it possible to overdose the birds on this medication using the stated directions? 2) The bottle of Corid gives directions for calves not chickens. It says a 16oz bottle will treat 100 gallons of water. I only have a 1 gallon water container, so I need .16oz (that is a very small amount). Is this really the dosage you all use for chickens?
