How to keep water in this exact container from freezing in Midwest winter?
I have this exact system of waterers for my quail hutch. I’ve kept quail this summer, and I’m preparing for the winter. It can get very cold here in the Midwest, and I’m worried about my ability to keep their waterers from freezing.
(I can’t bring my quail inside a shelter over winter)
Help me brainstorm some options for this 1 liter watering system to keep from freezing?
