Scott, all situations are different, but I find that If I remove their sticks, they just keep on building. Just today I took out two dummy nests (all sticks) and had done so previously, along with a HOSP or two’s nest. My blues are out teaching their newly fledged babies right now, but I suspect they will try another nest soon, and I sure want them to have access to at least one box. But I, too, usually leave them alone as long as possible when I have eggs/babies. Right now all boxes are empty, so I remove sticks.
