In order to learn about your bees, I think it’s good practice to look at your broodbox every 2 or 3 weeks. For now, just see if your bees got started on your flow super.
In spring you may want to look at your brood more often to see if they get ready to swarm, but now just give them a bit of time to move up. Not sure what the nectar flow is like where you are.
Your bees may start working the flow super or just keep the brood fed.
You definitely want to look at the brood if they don’t go up sealing the flow frames. Then you need to ensure your bees find enough food.
If not, you need to feed them and take the super off for that.
I’m in Northern NSW and it’s so very dry. Usually we are in a summer dearth in the mountains, but this year there is enough for the bees to still increase their weight by 500g daily, and the nucs are growing fast.
It very much depends on your locality and if the bees find food.
I don’t have a schedule for checking my brood, but if you are new to beekeeping, check every 2 to 3 weeks for now, so your experience grows with your colony.
