April why dont you go with top feeders? they are easier to refill (without a suit or vail) and you dont cause robbing like you do with a entrance feeder.
Actually I already have top feeders but I have heard some say how much of a pain it is to inspect the hive with these on. I will be getting my first package of bees next week and another package next month and thought that maybe until the colonies get built up a bit it would be better to use an entrance feeder since I will be making frequent inspections at first. Any thoughts?
