Eye Infection

Eye infections can be viral, bacterial, or fungal. They are called different things depending on the location of the part of the eye affected. For example, when involving the conjunctiva (the membrane of the inner eyelid and the inner corner of the eye's surface), it is called conjunctivitis (otherwise known as pinkeye). When the cornea is involved, it's called keratitis. This is just two examples of the most common types of eye infections found in ducks. There are many other parts of the eye that can be affected. Eye infections are also classified according to the cause.

  • Observe flock behavior daily---to look for any signs of (even seemingly small) aggression towards other flock members, as it can quickly escalate to an eye injury, loss of an eye, and even death.
  • Provide shelter that is large enough for all flock members to go in during strong storm events, as high wind can increase the risk of sand and other substrate particles blowing in the birds' eyes.
  • Do not allow large concentrations of dust to accumulate in duck houses by dusting regularly (however making sure that no ducks are present in the area while dusting or sweeping).
  • Be mindful when mowing the lawn or when using landscaping tools while in the vicinity of the ducks.


Risk Factors

  • Windy days
  • Mowing the lawn and use of landscaping equipment around ducks
  • High accumulations of dust
  • Eye trauma
