Eye Injuries

Eye injuries can occur relatively commonly in chickens. Injuries to the eye can involve the eyelids, the bones surrounding the eye, and the eyeball itself. There are many different forms of eye injuries, which can be mild to severe. However, even in cases where trauma seems minor, every eye injury should be given immediate veterinary care. You may not be able to tell how bad the injury is just by looking at the chicken's eye.

Eye injuries in chickens occur when something comes into contact with a bird's eye and causes damage. An eye injury may occur during fighting among flock members, especially when multiple birds team up against an individual. Dirt, excessive dust, insect bites, sharp thorns, and even straw can injure a chicken's eye. Chickens can also run into or past a sharp object that injures their eye.

Signs of Eye Injuries in Chickens

If your chicken has an eye injury or other eye problem, there are several different signs you may see. Signs may be present in one or both eyes. The most common signs of eye injuries in chickens include the following:
  • Swelling of the eye
  • Excessive tearing
  • Bleeding from eye area
  • Sunken-in appearance of eye
  • Inability to open eye
  • Squinting or twitching of eyelid
  • Cloudiness or color changes to eye
  • Rubbing eye
  • Prolonged pupil dilation, constriction or other abnormal pupil appearance
  • Rapid blinking
  • Yellow or greenish discharge
  • Bloodshot or red appearance to the white part of eye
  • Redness of the mucous membranes around the eye
  • Asymmetrical appearance of eyes
  • Light sensitivity
A direct or indirect blow to the eye from another rooster's sharp spurs or from pecking with a sharp beak can cause a simultaneous laceration in addition to bleeding inside the eye from the force of the strike. The blood in the eye can cause increased intraocular pressure, which can result in permanent vision loss. Eye injuries can also progress very rapidly and are often quite painful.

The following are some of the most common eye injuries seen in chickens:
  • Corneal laceration: A cut or scratch to the eye surface.
  • Corneal ulcers: May be from debris.
  • Puncture: Often from a sharp spur, beak, tooth, claw, or foreign object.
  • Eyelid tear: Often from eye getting caught on something.

Supportive careIsolate the bird from the flock and place in a safe, comfortable, warm location (your own chicken "intensive care unit") with easy access to water and food. Limit stress. Call your veterinarian.
Antibiotic eye drops/ointment
Vitamin B12An ophthalmic solution containing 0.05% vitamin B12, 0.5% taurine, and 0.5% sodium hyaluronate, given four times a day for 10 to 30 days, helped corneal nerve regeneration in rats after corneal injury.

Surgical eye removal (enucleation)
May be indicated in severe cases.



  • Do not mow the lawn or use a leaf blower near chickens
