Re: Should I add another brood box?
Pretty good questions there. Lets see if I can help answer any of them. lol.. I'm going to go in reverse here.. "How do you tell when there is a flow going on?" - The way I can tell is the activity on the landing board of the hives. When the bees fly in and out so fast and the air is full of bees contantly on their way in or out, you have a GOOD flow going on. When they set put and don't fly much, you have a dearth. Another way to tell is how quickly they pull comb. In a good flow the bees will pull frames of comb out very quickly, where in a dearth you will get lucky at times to have them even look at a new frame.
Now for the first question. "To add another box, or not to?" That is highly dependant upon what your goals are at this point. Since you want to do something, this is an option to get your honey supers pulled and ready for next year's flow in spring. Storing those or allowing the bees to keep them on the hive for the remainder of the year is the question you have to figure out. If your bees are pulling wax, it is easier to get them to keep doing so now rather then wait and them not want to do so later.
