What causes eye problems in my ducklings?
A possible cause is dust in the air but the main cause of this is high levels of ammonia in their pen from their droppings. You need to increase
ventilation and add more bedding. You can also sprinkle ferrous sulfate on the bedding before adding fresh bedding. Ferrous sulfate is a fertilizer
that binds to the ammonia and prevents if from volatalizing. But the best is to increase ventilation.
