OK I guess I was worried unnecessarily, when I opened the beer and took a big whiff, I got a nose full of alcohol vapor, so the yeast survived! I also took a hydrometer reading (1.024) but I must admit I don't really know what that means yet. I just moved it to a carboy after 10 days and will leave it there another week or so. Also after transferring it to the carboy the airlock started bubbling again, so maybe it was the seal on the plastic bucket not being air tight.
So you guys are right the lack of airlock bubbling wasn't a good indicator of anything. Thanks for the info and help.
