Dalon, yes still plenty of drones here too and more hatching.my point was more as to things you should be watching as seasonal indicators. Yes one drone being kicked out of one hive doesn't mean pack your bees down its winter.just keep your eyes and mind open.
Bee s are photo sensitive that is they make changes in the hive as to the lengthening and shortening of the amount of daylight hours. End of winter as the day length increases so will the brood, as the days shorten they will reduce the brood area, etc etc this cycle affects the swarm too.
As I alluded to in my last post there can be many reasons as to why a hive will swarm, need more space, reproduction, leaving because of destruction of the hive, environment etcetc. The way they swarm and the timing tell you a lot about the hive. If we have a hive trying to swarm in mid January/February it will not stay, it will settle in one spot then another.so at the end of the day you get it into a box when you come back tomorrow it will be on a fence post or up a tree again. Then during the day it will fly up and down amongst the hives a again settle some where. Best thing I've found is to throw I t into a strong hive and let them sort It out. It will be a faulty queen causing the issue.
Mikeboyle check that your mates swarm may have been there for quite awhile and as they have made home in a roof cavity this hot weather has them hanging out the front as the tin roof has gotten too hot for them etc.
Spring swarms will almost always be better than a summer swarm. In spring the are swarming with the conditions, that is longer warmer days growing floral supplies. In autumn they are swarming against the condition s, shorter days will they have enough season left to build up enough for winter survival etc.
