So this is one type of feeder I am using in my hives. I got the idea of a youtube video. Seems to work well and I added some screen so the bees don't drown. I don't like having to go into the hive every time I need to refill, but I can't leave sugar outside the hive b/c ants and other pests are very prevalent here in the tropics. It looks a little ghetto but works well.
