When you become familiar with a high quality food, you start to notice the difference in taste or texture while eating the same food of a lower quality. That has been my experience with chicken.
If you usually buy the cheapest chicken because it is on sale or you buy chicken in bulk, consider upgrading the quality of your chicken. You will see and taste the difference.
Cooked poor quality chicken tends to exhibit discoloration on the skin; tends to have a rubbery or tough texture; and/or tends to have a dry instead of moist taste. Also, cooked poor quality chicken may be difficult to remove from the bone while cooked high quality chicken tends to fall off the bone.
Bottom line: upgrade your chicken because your health is worth it.
