There is a pigeon in my house that hasn't come back after flying for two days. The boss with his neck closed and his mouth open can't eat normally. What kind of disease is this?

Your pigeon may have trichomonas infection, which is a common pigeon disease. Trichomonas infection can cause a cheese-like lump to block the pigeon's mouth or esophagus, making it unable to eat. It is suggested to take the following measures in time:

1. Remove cheese-like lumps: Remove cheese-like lumps from pigeon's mouth with cotton swab or round-headed medical tweezers, and then apply iodine glycerin or iodine wine several times a day.

2. Drug treatment: Metronidazole was used, and each pigeon was fed 1/4 tablets every morning and evening for 3-5 days. Pass 1 day of clear water and 1 day of liver essence electrolyte water. If necessary, it can be treated with Rijunsha, and each pigeon is fed 1/2 tablets every morning and evening for 3-5 days.

3. Pay attention to prevention: pay attention to prevention at ordinary times, regularly remove the hard lumps in the pigeon's mouth, and use probiotics or beer yeast for conditioning.

If none of these measures can improve your pigeon condition, it is recommended to consult a veterinarian for further diagnosis and treatment.
