Im a new beekeeper and I just installed my nucleus colony 2 weeks ago. They have already drawn out wax on about 80 percent (probably more now) of the frames I added. I want to add a second deep on top for them to expand but the temperatures are supposed to be a bit chilly after I was going to put the box on (lows in the 30s and 40s). My concern is adding it on and the bees having trouble regulating the temps in the expanded hive. This weekend is the only time I can get up to my hives for the next week or so, any suggestions as to what I should do?
