Winter Check-in

I have been quiet on here for a while - so have the bees. I went out today and replaced the feeders on the hives (quart jars filled with sugar water). Two of them were empty and one (Hive #4) was still full. This is the second time I have gotten this result, I am hoping that Hive #4 just doesn't like sugar water instead of a more deathly answer. I will not go in them until we get a really warmer day(in the 40s here). That's all for now.
