Clinical signs of coccidiosis can range from none to bloody droppings, watery diarrhea (flushing), weight loss, paleness, sick bird appearance (ruffled feathers, huddling, depression). Affected birds do not eat and will sometimes march from feed pan to feed pan, vocalizing a high pitched cry. Mortality can range from mild to severe, depending on the species of coccidia involved. All ages of poultry are susceptible to infection, but the disease usually resolves itself around 6 – 8 weeks of age. The birds are most sensitive between 3 – 5 weeks of age, when the coccidia ; are the most numerous in feces or litter. Many times the disease is subclinical and the flock may only show poor weight gains or feed conversions at the end of grow-out.
