I guess you never got those bargain colonies last year. Seems like I remember you had a pretty good price on some existing colonys.
I would probaby wait until fall at this point. I don't know your nectar flows out there on the coast, but I would guess it has started. The swarm queen was able to make enough brood to cause a swarm, may as well give her a chance to carry on. Swarms have always seemed even more industrious than normal to me, and I like to watch them grow.
