I have a standard top feeder for an 8 frame hive. It has the two chambers on either side of the bee access and has wood floats in each chamber for bee access. Has anyone experimented with adding any kind of automatic filling device for this type of feeder. I am using it on a hive that I have constant access to so it is not too difficult just to open it up and fill it. However, I may consider using this on a hive that I have on a farm where I might not access it but every two weeks or so. I notice that my bees in the city can empty the feeder in one week. And I have discovered that an empty feeder is just asking for all sorts of unwanted guests (beetles, moths, ants). The bees cannot protect the area below the float once the feeder runs dry and it makes an excellent SHB breeding ground. My idea would be possibly to attach a siphon system from a large container of some sort to provide a continuous level of syrup in the feeder.
