I have played with different ways to feed bees many times. What I have noticed is that weak colonies won't move far for food. Sometime a feeder can be a frame away and they will not touch it. I read a article where someone filled combs with sugar/water and placed them in there hives. So I tried this with a couple weak hives along with a couple strong colonies. The weak ones thrived from this and the strong ones had plenty of food but I think this may help them in early spring to get a jump.
Here is the a video show how to fill frames: http://youtu.be/qAyx4MNLAQE
