My third havest

Hiya @Fredrick_J_Dunn, great vid, it’s good to hear the success.
Couple of quick questions for you or anyone else who can answer about your top entrance.
When the foragers bring back nectar don’t they give it to the house bees who in turn transfer it to the cells?
Do the foragers carrying pollen use the top entrance then go through the qx to the brood box? I’m assuming they don’t put it into the FF.
Thanks.
