Spring is Coming!

It's only about a week until spring and the bees are so active! It's great to see, especially Cam's hive. The dysentery seems to be improving and there's less smell. I've peeked until the covers a couple of times and both hives have 6-7 frames of bees as well as capped honey still in reserve. The weights are going down quickly though. I'm assuming they're raising more brood and consuming a lot more honey and pollen now. Both hives have lost almost half their weight compared with January.
The pollen is coming in though! I think it just started: the filbert tree right behind the hives is covered with catkins that have light yellow pollen. The weather has been in the 50s during the day so lots of bulbs are coming up. I saw pussy willows blooming down the street and my snow drops started in late Feb.
I renewed my apiary registration with the state this week. Our second year class starts this week and I can't wait. I think I've already read about a third of the 'Hive and the Honey Bee' text. I have so many questions! When to take off the entrance reducers? When/if to feed pollen patties? When/how to start mite management (powdered sugar?) and measurement? Whether to make a split and/or start a nuc? I made up a preliminary spreadsheet to get organized but it needs some fine-tuning. I'm hoping that keeping good records will serve in future years.
