Taste is really related to breed
I have three breeds listed here The names of the breeds are actually directly translations from Vietnam There's local and crossbred which are types of free range chicken and also industrial chicken I have a scale of different tastes It's a subjective scale. Basically it's based on several conversation I had with Vietnamese consumers and my experience there So local is the tastiest going down to industrial which is largely considered to not be that tasty at all This is reflected in the price. Local chicken is quite expensive, Industrial is not But remember, even though local chicken is more expensive and crossbred chicken is more expensive it still makes up the majority of at-home consumption Safety is the other factor right now Grocery stores have a very small market share for chicken and private certification generally is very rare Most chicken is purchased in open-air wet markets or even illegally live
