So I'm in upstate NY with still very cold weather but thankfully mostly booming hives. Most but not all of them are coming up to the top to feed in the shim area during the day, even with temperatures in the single digits. My question and concern is this - given low temperatures I'd like to just open the top very quickly and slip food in - usually winter patties or sugar blocks but increasingly pollen patties - but the bees are rarely centrally located so I'm worried I may squash a queen. My specific question is are queens typically up at the top or is there an "advance foraging force" that heads up to the top to feed leaving the main ball down below. I'd rather avoid squishing any of them but for a 10lb patty block I'll accept a small risk of casualties but I have no idea if that feeding group is likely to have the queen up there too, making me therefore be way more careful.
Many thanks for your answers in advance.
