Oral Canker

Oral Canker

Oral Canker (Avian Trichomonosis) is caused by a protozoan parasite (trichomonas gallinae) commonly found in pigeons and doves.

Symptoms

  • Yellow cheese-like plaques on the roof of the mouth, inside the beak and sometimes spreading to the oesophagus (Figure 1).
  • Birds may have difficulty swallowing.
  • Food and water intake may drop.
  • Lethargy and weight loss may be noticed.
  • Birds may have difficulty closing their beaks (Figure 2).

Causes

  • The Trichomonas protozoa is extremely common in wild pigeons and doves with 80-90% being carriers.
  • Pigeons feeding or drinking from hen feeders easily spreads the parasite.

Guidance

Note that this home remedy is not intended to offer a cure or replace veterinary treatment, but may alleviate symptoms where no professional support is easily available. The suggestions are based on experience gained with our own hens.
  • Isolate the bird and provide easy access to food and water.
  • You will need to seek veterinary advice for an appropriate treatment.
  • Home remedies include:
    • Garlic extract – 200mg/kg body weight daily.
    • Apple Cider vinegar in drinking water may help (15ml per 4 litres monthly).

Prevention

  • Do not allow hens to drink from the same water source as pigeons and doves, this is the main way that Trichomonas is spread.
  • Restrict wild bird access to feeding areas.
  • Routinely clean feeders and drinkers.
