Good Afternoon everyone,
Totally new Beek question I know, but I am worried about the behaviour of this hive. I captured it as a swarm on the 1st October and its been settling in nicely. Good brood pattern, the one super I put on it about three weeks ago with new foundation is now built out with approx the top 1/4 of the frame capped and the rest of frame with a good amount of honey.

ImageShack.usI put a 2nd super on this morning, but am concerned about the number of bees hanging out the hive entrance in the afternoon. It is hot here in Brisbane now (getting towards 35/36 C the last week or so). Are these guys getting ready to swarm (so soon after only being captured a month ago), or just hanging out the front of the hive due to heat inside the hive and trying to keep things cool?
