Fairly new beekeeper here. This has been a crazy start to this year - colder weather than normal. Only had a couple hives that survived - one is now gone and the other the bees are going in the top under the lid. They won't go in the bottom. I haven't ever seen this. I am loathe to take it apart to see what's going on... but I will if needs be. Does anyone have any idea what might be happening?? Thank you.
