Treatment

Treat the whole flock with amprolium (Corid) in the drinking water for 5 to 7 days. Do not give B vitamins during Corid treatment, they cancel it out. Once finished, follow with probiotics and vitamins to rebuild the gut. Move birds to clean dry ground.

Prevention

Keep brooders and runs dry, the parasite needs moisture to thrive. Use medicated chick starter unless you have vaccinated chicks. Clean waterers daily. Rotate runs. Do not overcrowd young birds.

Typical recovery

5 to 10 days with prompt care.
