Congratulations on starting up a hive. I started mine last year and the information and help from people on this forum helped tremendously. I have four friends at work that I used as mentors but the people on the Forum were there for me at all hours of the day and night.
I agree with @Dee, @Dawn_SD and @Martydallas, starting with a nuc is the way to go for us newbies for all of the reasons Marty pointed out.
Here few more things to think about before spring gets here and your bees arrive. The person I bought my Nuc from said it would be ready at a certain date but the weather was great and the nuc was ready two weeks before the date they quoted. Luckily the spot where my hive was going to be set up was all ready to go or I would have been in a panic.
Picking up a Nuc for the first time was interesting. I was glad that I had a pickup truck with a canopy. The nuc was sealed very good but there were a few loose bees and if that had happened inside of a car it would have distracted me.
Keep your Nuc Box…when my bees swarmed later on in the summer I was able to capture the swarm and started a second hive. And you may want to have a second hive ready in case you need to split your hive or if they swarm.
Practice keeping your smoker lit a few times before your bees arrive.
Figure out what your going to use for an entrance reducer. Many of the standard reducers don’t fit the Flow Hive entrance. There are a lot of good ideas on the forum for making entrance reducers. I had to try to fit the one I made to my hive entrance after I got my bees.
And finally, find a place to set up your chair because your going to be spending lots of time watching your girls do their thing with your favorite beverage in hand. Its addicting!
