great thread to start mama! so all can learn about the different types of feeders. some of this will be regional for all of us, and to some degree a personal preference, or what works for us in our areas.
because i am in the north cold country, like perry i use the buckets over the inner cover. these are fool proof and right over the bees, unless you forget to check it for leaks. i don't like the boardman feeders, this causes too many problems for me with pests and robbing. the only time i use boardman feeders is to place water on a hive, a new divide, or a nuc, works great for this.
ps the boardman feeders are what the other beeks are referring to as an 'entrance feeder'.
