CAN ANYONE PROVIDE ME WITH THE CORRECT DOSAGE OF CORID 9.6 AMPROLIUM FOR PREVENTATIVE USE/ BUILDING IMMUNITY IN BABY CHICKS? I have healthy 6-day old chicks on non-medicated feed, but have had two bad strains of Eimera (coccidia) diagnosed in my older hens in the past, which has wreaked havoc on the health of my flock. It is unavoidable that the chicks have been or will be exposed to it. I had purchased the live vaccine Cocci-vac D, but have now been advised by a vet from Fort Dodge Animal Health NOT to give the vaccine but rather to give the mild, preventative dose of Corid to the chicks while they build up their immunity. I have Corid 9.6 Amprolium. The regular (treatment) dosage is 9.5 cc (1 tsp) per gallon. Can anyone give me the correct dosage for PREVENTATIVE use? Thanks!!!
