I've got my hives out on an alfalfa farmers land and he recently set up a corn feeder for some type of bird, sage grouse or something not sure exactly what but in any case it's full of dried corn kernels. The other day he was out there and called me completely bewildered at what he was seeing. There was a cloud of bees around the feeder and at first he thought they were swarming so he was going over to look at them. The feeder being on a timer kicked on as it routinely does and spread the corn kernels everywhere. Well much to his surprise a mixture of corn and bees were ejected all over the ground and the bees followed the corn to the ground. He said it looked like they were eating it.
For clarity all of the hives out at this location are Carni's and they're all first year packages. None are big enough to have swarmed especially during this heat and with a dearth on right now. All of the hives have at least an unfilled deep on top of the hive to fill so room isn't a problem.
