A common sign of frounce is what?

• A. Sneezing
• B. Bald patches
• C. Yellow plaques in the mouth
• D. Diarrhea

Answer: (C)

Frounce is a protozoan infection that targets the mouth and throat of birds. The most noticeable and characteristic sign is yellow plaques in the mouth. These plaques are usually yellow to white, cheesy in texture, and can be scraped off, leaving reddened tissue behind. They often cause drooling, discomfort, and difficulty swallowing, and can lead to weight loss if not treated.

Sneezing points to respiratory issues rather than this oral infection. Bald patches come from feather-related problems such as mites or molt issues, not frounce. Diarrhea involves the digestive system more broadly and isn’t the typical presentation of frounce.
