Night of the living yeast?

[Earl_Grey]

So I've had a lager going in a secondary at 34F for a couple weeks now. I have it hooked up to a blowoff tube and today there was some activity. Is that normal or out of the ordinary?

Never done a lager (nor interested) but some activity after primary is normal. Love this Q lol

define 'some activity'
it was likely just dissolved CO2 escaping, and not actual fermentation activity
give the carboy a good shake and you will see more activity
