I have four hives that I thought were packed with honey, but the bees in all the hives have been clustering over the top bars at least for the past few weeks, so I decided to play it safe and feed them. I used the dry sugar method over newspaper today and it went well as far as I can tell. (Sure beats cooking up hard candy for them.)
While I was doing this, I noticed the bottom entrance of one hive was sticky with honey. (I tasted it. It could have been a mixture of honey and sugar syrup.) This is only my second winter of beekeeping, so it's the first time I've seen this.
What does a bottom board sticky with honey in the middle of the winter mean? Could it be a mouse stuck inside the hive chewing open the honey comb? Is it something I should be concerned about?
