yep Buzz.... What Robo Said!!
General with a one story and especially a 2 story hive in the first season (and yes I did get a very late start with receiving the packaged bees) you often DON'T see the population build up fast enough to warrrent OVER-POPULATION and thus swarming.
It takes a good prolific queen, great wax production, a good balance of brood and food storage: everything has to go right in a shorter season to see swarming the first year. So yes... swarming in season one is "Generally" a good sign that all is fine in the hive!
You can of course build upwards and kill of swarm cells if you wish to build a stronger hive, but going from a 2 box hive to a 3 box hive late in the year (just to prevent swarming) can be a mistake too - you may NEVER reach the full drawn frames you intend to build out and you get left with a lot of bees to keep in a 2 story high hive that CAN'T hold enough food source to feed a cluster over a long Winter. Hope that makes sense.
Early swarms, or at least swarm conditions can be dealt with much easier by building upwards, but later swarms are much harder to deal with unless you have an extended Fall with a continuous food source. Actually, food availability is a major factor in the late season swarms.
Thanks Robo for the kind words and yes it does feel very good to be typing again. For a number of weeks I couldn't concentrate enough to sit at a keyboard and do anything. I've kept myself very busy working around the yard and doing well. Thanks
