I have three colonies in two hives, the first colony is 7 weeks old, started from a nuc. I have been adding new bars into the brood nest every week or so and haven't seen any queen cells. But today I look off my balcony and this is what I see.
I'm a little concerned. It has been three days of rain that just let up a few hours ago. Could they just be flying more as they see it's the only time to get out and get some food? I do feed them, about a quart of 3:2 syrup every day or every other day.
Should I be concerned about swarming?
