What color is bad chicken?

The colour usually isn't the main criteria for "bad" chicken. It might still LOOK good, but the odor is the thing. Chicken should be discarded after refrigeration in less than a week because the bacteria in chicken makes it inedible very quickly.

Some visual signs are dry edges, a pinkish tinge to the edge of the meat, but above all..the smell. Your nose will alert you to spoiled meat quicker than visual clues.

To be safe, don't store chicken in the refrigerator more than three days, or in the freezer more than two months.
