I don’t know that the order is important but it would be best if you added one super and waited to add the second until the first was at least 80 covered by bees (or filled with honey).
IMO if I did those 2 exact boxes. i would put the comb on first over the brood nest, to keep the brood nest open, the first flow will not go into foundation, and they likely will not carry dandelion nectar across the foundation. As well when they start the foundation you know they need the space.Probably a frivolous question but I will be stacking on a medium of drawn comb and a deep of just foundation does it matter the order what’s the most effective way. I want to say drawn on top so they have to work on foundation but I don’t want the top drawn stuff to become a shb hiding spot. Flow here will start after this front and really kick into gear about may 1 when tallow blooms.
