Swarm swarming

[sigrami]

Did a beekeeping course in April.
Beginning of May was given a swarm from an unknown source.Everything seemed fine but in the last 4 days the original swarm has swarmed 3 times.
Any ideas????

what are you keeping the swarm in? a langstroth nuc? or a full sized hive?

what have you found inside on inspection?

Langstroth hive.Inside 4 old frames that the swarm came on and 4 other frames covered with comb.2 still empty.A week ago found a couple of queen cells which disposed off,been away for a week to a welcoming from bees everwhere.
