It is a secret, how big the packge is. I guess that it is 3 pounds and that covers/occupye . Actually it is is an artificial swarm. Nuc has brood with it , and how many.
As you see, weather is not marvellous in UK. Small colony will not stand what ever. Its build up is poor if the colony has too much space and too much ventilation.
When I started beekeeping, I bought plenty of swarms. I found out that 8 pound swarm was the best. It build up fast and it brought honey 40kg in one month. It payed back the price at once.
After 4 weeks it had 3 boxes bees.
One box swarm has difficulties to handle honey. It is able to bring honey but it needs brood space than honey space. - only way is to take honey frames off and give new combs or foundations.
But before the new bees emerge, the colony has lost half of its bees. Brood makes heat as much as a resting bee.
The colony cannot make much because bees are not enough, they are old. Just waiting new bees.
Too few space, good flow -- swarming...bees escape....
Too much space -- poor build up
3 pound swarm - - slow build up , nervour beekeeper, stupid advices
