Nuc into hive

[Finman]

You've lost me now, aren't you saying the same thing? Unless they are outgrowing their nuc (bursting) there is no need to transfer them to a hive.

I do not know what I said, but I have same opinion.
It depends the amount of brood.

No one knows the situation if the owner does not count amount of brood.
And from where nuc gets brood if others do not have them.

Situation in UK is now very uncommon.

Apologies Finman, I thought we were saying much the same.

I'd fill the void behind with some form of insulation, kinda pointless unless you did.

Filling the void with insulation but allowing heated air to circulate past the same roof and wall area is pointless.
