I have some bee hives. On warm days, I always have lots of honeybees from my hives in the feed (not unusual at all if hives are within a couple of miles of you). My chickens ignore them. I have Guineas too. My hives are enough distance away that the Guineas don't venture there. If the Guineas pick off some that are in the feed, I figure that is just nature. Honeybees won't be aggressive away from their hive so no problem there. Honeybees will forage for several miles from the hive. My bees are doing the winter thing -- clustered. I don't find them coming to the chicken feed or out in about unless it is over 55 F.
