Chicken in the fridge for over 2 days

I bought some raw chicken breast and I put it in a slow cooker this morning which would be the start of the 3rd day of it sitting in the fridge. It was 2 days past the sell by date. I would hate to waste it. I didn’t notice a smell. Would you eat this delicious meal I’m preparing? Brown sugar BBQ sandwiches.

It's fine. Rinse it off and no smell then it's good to go.

Smells fine, it is fine.  Sell by is usually the day they put it out.  Probably good for 4 or 5 days.  Really depends on how consistently cold you keep it.
