Patrick, I also live in East Wenatchee and I have several Hummingbirds. I did put out feeders because they need the nectar to keep up their energy to make it through the winter. I wrapped the feeders in Christmas lights to keep them from freezing or you can bring them in at night but you'll need to be an early riser because they start eating at dawn. I've seen them as early as 6:30am. Also you can read online about wintering hummingbirds and how to take care of them. Happy Humminbirding, Barbara

Anna's are year round residents across much of WA state. I would advise keeping feeders up and full (and unfrozen) as long as you see the birds visiting them. While they prefer the milder coastal areas, they are not uncommon winter residents in parts of eastern WA as well.
