Newcastle disease was found as most prevalent (11.35%) among the viral diseases. On the other hand, colibacillosis was the highest prevalent disease accounting for 15.34% among all bacterial diseases. Moreover, 22.48% cases were other types of infections (mycoplasmosis, coccidiosis, aspergillosis, deficiency disorder and internal parasitic problem) and 2.73% cases were unidentified. The highest numbers of diseases were found in the age group 21 to 30 days (23.53%) whilst the quails aged between 11 to 40 days (59.67) were most vulnerable to various diseases. The highest occurrences of diseases were found in rainy season (39.29%). It can be concluded that Newcastle disease and colibacillosis are the most frequent challenge for the quail farming in Bangladesh. Strict bio-security and proper management system might effectively reduce the incidences of the reported diseases.

Thank you, my friend.

I've experienced that they are more prone to Coryza and other upper respiratory conditions than chickens, but in general are fairly healthy. Staph infections of the skin are not uncommon ("bumblefoot" more so than layer chickens in similar housing strategies).

Certainly keep them on wire and reduce vectors. Because they keep well at high stocking densities, this leads to rapid spread of pathogens once they are established.
