I’d avoid feeding honey to bees. It risks spreading disease; is more likely to induce robbing than sugar syrup and rather surprisingly they don’t do as well in it.
Feeding the powder.
If you’re at a serious scale this is how Victor and Dave feed it:
At a smaller scale if you can find pvc plumbing cheaply this is a common technique (that I will use when I stop being lazy)
I used a clear plastic tub that I drilled holes in the side of so I could see what was going on; they could get in and out of easily, was weather proof and not too accessible to other critters that might like a diet of pollen substitute.
I tried variations of hanging it from a tree, sitting it on a hive and now… on top of some racking under the pergola at the back of my house. If they want it they’ll find it wherever you hide it.
I would think rubbing it into a brood frame would only be of relevance if you have seriously miserable weather so they can’t get out. I’d prefer to let them access it if/when they want tit rather than force feed it to them.
