Smelly chicken - is it unsafe? I have a fresh raw chicken breast that has been in the fridge covered for a few days (still in date) that doesn't smell 'normal'. It doesn't smell terrible but it had some clear bubbles/dots on it that wiped away when I touched them with my finger which I haven't seen before, and I'm not used to having a smelly breast so to speak.

I've never smelled bad chicken before so I'm not sure what to look for. Obviously if the meat is spoiled I won't cook it.

Are the smell and bubbles/dots a sign it's become unsafe, or something normal and safe? I've had breasts in the fridge for longer that haven't gone bad.
Not trying to be flippant, but to me it is easiest to apply and old kitchen rhyme to meat:  "When in doubt, throw it out."

Chicken is notoriously prone to spoilage.  Having suffered from food poisoning more than once, for me it is a zero tolerance.  Unusual smells on raw poultry, unexpected discolorations and such make it not for my consumption.  The dots, well, I would have to see them because they could be any number of things from congealed fats to fungus.  Without personal evaluation it is an unknown to me, and unknowns are potential danger in food, especially raw meat.
