I recently added a second brood box when I combined 2 hives. I added a second box to my good hive one day when I decided to combine my failing colony into my strong one. I took off the second box and combined the two. At the time I decided on the second brood box, my strong hive looked awesome. Lots of brood, eight frames drawn out, tons of pollen and capped honey. I was checking the hive the other day and felt a bee crawling on my finger as I was holding a frame and low and behold it was the queen. Can't find her when I look for her..lol. She was checking cells so obviously she is looking to lay. Should I bother looking in the lower box for awhile or focus on the upper. The bees have some gnarly comb to straighten out in the top one and I'm hoping to see new brood in the next week or so.
