Hoping an expert can chime in quickly to help you so that you don't lose anymore chicks. How many do you have left and how old are they? When we first noticed we had a problem, we replaced all their bedding and cleaned out their waterers and feeders. We scoop up any stools that we see and have been overly monitoring stools, behavior, and their eating and drinking habits. After looking through a lot of threads, it does look like coccidiosis can kill chickens with little to no symptoms, but weak chicks and bloody stools can be a dead give away. We found Corid powder at our local Tractor Supply in the cattle section. None of the employees knew what it was or where to find it. We add 1 and a half teaspoons to 1 gallon of water and change daily for 5 to 7 days. We are keeping them in their coop and not allowing them to free range for the time being so we can ensure the only water they are drinking is medicated. We treat the whole flock. We have not lost anymore chicks and they seem to finally be improving and on the way to recovery. Wishing you the best of luck.
Definitely not an expert, treating mine now with corid. No blood in droppings but wet and foamy. I've been fighting this since I got poults from a hatchery a week ago I'm not blaming the hatchery it was so hot during shipping. Birds seem healthy except for droppings.
I see you use 1 &1/2 teaspoons corid per gallon. Dosage I found was 1/2 teaspoon per gallon. Mine are chicks, am I not giving them enough?
