I need to add a second brood box to the swarm hive. The only extra super I have right now has foundation that is wireless. Will that work for the brood box or is it better to have wired foundation?
It will work just fine.
Wireless will work but I always wire brood foundation just to keep it straight. In the hot NC summers, I don't want the foundation curling and resulting in the bees drawing some really strange comb.
