Home made bee feeder

I have two hives this year and I want them to make it through the winter. On advice of a local bee expert I took the boxes with honey and condensed the bees into a single box each. As such they absolutely need to be fed. I wanted to be able to feed them without having to open up the body of the hive while it’s cold out. I also want to prevent the bees from having access to the empty box where the food is to be. Being cheap, and searching the internet for various ideas, I made this up out of items we had in the garage.

Strips of wood, this is cut from our porch. I cut them into 1 foot pieces.
Excess window screen.
I stapled it around the wood long ways first.
Then I folded over the ends and stapled it. This makes it firm and helps prevent the bees climbing out the ends.
Nice, firm bee feeder.
Can hold 3 jars along the length.
AND it’s in.
