There's nothing wrong with last year's queen's the probability of them swarming if looked after properly is very small .
Depends on what your bees genetics are like.
My local mongrel bees are habitual bi-annual swarmers; regardless of the age of the queen....or how well they are looked after.
Not necessarily the case for mongrel bees in other areas, but a topic difficult to generalise about.
