Winter Check of the Hives

Today was a mild day of 43 degrees.  The wind had died down and cold single digit temperatures are expected to arrive.  I am a newbie when it comes to keeping bees and I have worried each winter.  Did I leave them enough honey stores for winter?  Did I close them up adequately? Will I have any hives alive in the spring?  We had some leftover comb honey I figured I could feed them if need be.  So I trudged out the hives and low and behold each one was more active then the next  they all seemed to still have a good amount of stores left.  I removed a couple empty frames and placed a few of the comb honey in some of the ones that seemed like they could use a bit more.  Now to hope for an early spring!
