Ok here is what I know..... new coop, new flock, first chickens we ever had. Have been in a large coop not outside. Moved to an old calf barn lot and let out two days. Have been feeding a starter/grower with a coccidiostat 'Amprolium" for several weeks. Still feeding but also gave one cup of scrach grains and one small cup (less then 1/4 tea cup) of oryster slees and grit. all feed free choice. Treated water today with an electrolyte powder. I also bought a bottle of liquid amprolium, but after reading the feed bag it said use the feed as the sole source of amprolium so i did not add to the water..... Droppings seem to have some blood. Do you think this is coccidiosis???? What is an emergency treatment option?
