Vent gleet, also known as avian candidiasis, is a common fungal infection that affects the reproductive tract of chickens. It is caused by the overgrowth of the yeast-like fungus Candida albicans. Here is an overview of the causes, symptoms, and treatment options for vent gleet in chickens:


  1. Immune system weakness: Chickens with a weakened immune system are more susceptible to vent gleet. This can be caused by stress, poor nutrition, or other underlying health issues.

  2. Antibiotic use: The use of antibiotics can disrupt the balance of beneficial bacteria in the gut, leading to an overgrowth of Candida albicans.

  3. Dirty living conditions: Dirty coops and runs can create an environment that promotes the growth of Candida albicans.


  1. White or yellow discharge from the vent: The most obvious symptom of vent gleet is a thick, white or yellow discharge from the vent.

  2. Swelling and redness around the vent: The area around the vent may become swollen and red, and the feathers around the vent may be matted with discharge.

  3. Loss of appetite and weight loss: Chickens with vent gleet may lose their appetite and experience weight loss.

  4. Difficulty laying eggs: Chickens with vent gleet may have difficulty laying eggs, or may lay eggs with soft or misshapen shells.


  1. Antifungal medication: Vent gleet can be treated with antifungal medication, such as Nystatin or Amphotericin B.

  2. Probiotics: Probiotics can help to restore the balance of beneficial bacteria in the gut.
