The term "Sonali chicken" could refer to a specific breed of chicken, a local variety, or a commercial strain developed in a specific region. It's also possible that it may be used as a brand name for a certain type of chicken product. Breeds and varieties of chickens can vary in terms of size, color, egg production, and other characteristics.
If "Sonali chicken" refers to a specific breed or variety developed for agricultural purposes, you might find more information from local agricultural or poultry organizations, research institutions, or government agricultural departments in the region where it is relevant.
For the most accurate and up-to-date information, I recommend checking with local agricultural authorities, poultry associations, or referring to scientific publications related to poultry farming in the specific region where "Sonali chicken" is used or referenced.
Keep in mind that the landscape of poultry farming and breeding can change, and new breeds or varieties may have been introduced since my last update
