All will be well, and that will be well is well.
So cool to meet a fellow South Dakotan, There's not that many of us.Thanks for your detailed post, that helps a lot! I live in SD too and boy it's cold here. We had a few nice days though
I'm near Silver City and shop in Rapid. If you do too, you can buy your grains at D&M Ag Supply. It's a lot easier to get into than the elevator downtown. Just head out toward the airport. They're on the left shortly after the overpass. They have a big yellow canvas tunnel shelter for hay, etc. They also carry Hubbard feeds, incl. waterfowl feed.
Since you're gonna be gone I would not start the whole fermented feed thing until you get back. That's too much to ask of a neighbor. You can try some active ACV in the water and see whether he'll drink it. It never seemed to bother my chickens but some birds refuse it. It would be easy for your friend to do, though. I would get a bottle of that and try it. If he still drinks the water, your friend can put some in easily enough. Be sure to get the mirror, though, if you can. That's a big deal for him.
