Although I am happy you picked up this swarm, Its not the best time of year to find a swarm. Although it could turn into a profitable colony next year, there are no guarantees that it will survive the winter no matter how much resources you put into it. A swarm at this time of year is not free bees. It will cost him. there is little chance that this hive will store enough for winter on its own so heavy feeding and frames of honey that could have been extracted will need to be provided to it. The bees in the swarm are the older field bees so major brood rearing will need to take place to get an abundant winter bee population. Hopefully you will have lots of pollen coming in this fall and feed, feed, feed,. You could provide it with a few framed of capped brood and give it a 2 to 3 week head start on the winter bee population.
