Will they or won't they?

So far, so good.  The bees are still alive.This winter with its crazy yoyo temperatures has to be hard on them, but they are still humming in there.  Hope they can make it. I can't open and feed them again yet.I lost the big hive, my original hive, quite suddenly at the end of last summer, and these, the new bees, didn't have long to get established, and God forbid, they may have been infected with the crisis from the other hive.  But so far, they're ok.  I'm tense about it.This is two bees at the upstairs door, walking around on the tarpaper the hive is wrapped with.  On warm enough days, a few come out walking around or flying.
