Your airlock is not a fermentation gauge, it is a VALVE to release excess co2. [/B]
If your airlock was bubbling and stopped---It doesn't mean fermentation has stopped, or is stuck
If you airlock isn't bubbling, it doesn't mean your fermentation hasn't started....
If your airlock starts bubbling, it really doesn't matter.
If your airlock NEVER bubbles, it doesn't mean anything is wrong or right.
Fermentation is not always "dynamic," just because you don't SEE anything happening, doesn't mean that any-thing's wrong,, and also doesn't mean that the yeast are still not working diligently away, doing what they've been doing for over 4,000 years.
The only way to truly know what is going on in your fermenter is with your hydrometer.
Like I said here in my blog, which I encourage you to read, Think evaluation before action
you sure as HELL wouldn't want a doctor to start cutting on you unless he used the proper diagnostic instuments like x-rays first, right? You wouldn't want him to just take a look in your eyes briefly and say "I'm cutting into your chest first thing in the morning." You would want them to use the right diagnostic tools
before the slice and dice, right? You'd cry malpractice, I would hope, if they didn't say they were sending you for an MRI and other things before going in....
Thinking about "doing anything" without taking a hydrometer reading is tantamount to the doctor deciding to cut you open without running any diagnostic tests....Taking one look at you and saying, "Yeah I'm going in." You would really want the doctor to use all means to properly diagnose what's going on. It's exactly the same thing when you try to go by airlock....
More than likely fermentation is done or close to it, and your airlock simply doesn't NEED to bubble any more.
And even if it IS done fermenting, that doesn't mean that the yeast isn't done doing it's job.
Just leave it alone for at least another 8 days OR MORE, they you can take a hydrometer reading and decide if you want to secondary it...OR you can do what many many many of us do and leave your beer alone for a month, that will let the beer finish fermenting and then let the yeast clean up after themselves, that way they will get rid of all the byproducts of fermentation that often lead to off flavors, and if new/impatient brewers move to soon, they end up stuck with.
Even John Palmer talks about this in How To Bew;

And, three weeks in the primary fermentor is usually not enough time for off-flavors to occur.
