Well it's cold out all my feeders froze solid and are currently sitting inside to thaw while the birds eat dry feed... Even if I can't figure out how to keep them thawed through the cold, it was still a pretty good run they will definitely come back out in the spring.
Next I'm going to try rotating the feeders. I'll bring out to warm ones in the morning ,bring the frozen ones back in the house to thaw and rotate each day....
Not as ideal as finding a way to keep them from freezing but I'm still working on something that's going to actually function in -20 and colder... There were no heated bases in the store today so I am SOL on that front...
