After losing my 7 month old peachick to what may have been coccidiosis I have been treating my 5 adult peafowl with 1 1/2 tsp/gallon water for 5 days now in their drinking water. Their poo is still a runny black, some with a little white in it. Is there something else I should be doing? Was the dosage correct? Should I continue treating with Corid? They are eating well and not lethargic (just fighting these dang fleas and gnats which I am fighting with permethrin and Ivermectin.) Any advice regarding the black poo?
