I'm not sure how to frame this question so please bear with me; I'm trying to figure out when they are going to change from making brood to focus mainly on building honey stores.

This is a new TBH, 24 days old. Begun with a single package. Because they are starting from bare bars, I'm feeding vast quantities of 1:1 syrup.

Here's what I'm thinking: The queen had to wait until the workers began building comb, then began laying with the goal of having the maximum amount of foragers available for the height of the nectar flow. I don't know the composition of the package, but certainly there were foragers in there, so they were available to gather some pollen/nectar (if any was available 24 days ago). But the majority of the foragers won't be available until (45-24= 21) 21 days from now. Hopefully we will be able to take advantage of the flow.

I'm feeding and she's laying. At some point the hive is going to realize the natural flow is going to ease up some time in the future, so they can ease up on making brood. I'm interfering because I'm making 1:1 available. So, what will case the hive to switch emphasis from brood to storage? The vast number of foragers becoming available? - Mike
