This is my first year at beekeeping. I spent a significant amount of time researching the subject and one thing was clear, newly installed packages should be fed to promote drawing out plastic foundation. Michael, I know you disagree. Most advocates agreed that internal feeding was preferable to the entrance feeders so I decided to purchase two wooden top feeders from Dadant. After only two weeks using the feeders I have given them up. The first issue could have been prevented if I had simply filled the feeder with water before using them to determine if they leaked because one did, both sides. The second reason and most important is that the bees filled the feeder ladder with comb and also the inner cover, more bees stayed in the feeders than were down below drawing out the foundation. I noticed the comb building early on and removed it but they continued to fill the feeders so I removed them. Two weeks with new packages and one package not really being fed because the syrup leaked out and all that wasted comb in both hives. I have since modified my entrance reducer and am using Boardman feeders. I am not having any robbing issues and the hives are doing real well. I think I will turn the feeders into quilt boxes, screen off the bottom and fill them with moisture absorbers for winter.
