I'm sure this will be one of many mistakes along the way. Anyway, I took my half-full top feeder off and sat in on the ground on top of the cover while I inspected my hive. After inspection, I looked down and saw the syrup full of drowning bees. I dropped an alfalfa stalk life line and saved all but two. I poured out the syrup and replaced the top feeder without the top cover to give the rescued bees a chance to dry out and fly out of there. Note to self: Put cover on top feeder after removal. What do make of this picture? Queen cell? Practice cell? Probably not a good pic, but the drone cells are usually greyish and this is more whitish.
