What does it look like? White across the top? Black on the sides? The fermented feed kills mold. I'd wipe the sides off and stir down. The white on top is the scoby and is the good stuff. It's ready to feed. You don't have to continue stirring daily like before just when you're dipping it out.
Actually, stirring before feeding is good. If you keep a drier mix, usually the top gets drier and there's a juicy layer further down. Stirring not only helps the consistency, but also gets the top SCOBY mixed back in. That's my two cents. I would never not stir before feeding.
