If I have 2 deeps, come spring my bees are in the top deep. so I read that I should reverse the deeps and start with the brood in the bottom. then in another thread I read about needing to make a "hole" in the brood nest to make room for the queen to lay eggs because they back fill around the top and keep making the nest smaller.
so my ? is, why not just let them in the top and as they fill the top of the frames it will push the queen and brood nest down naturally
