I have read that they don't like milo because it is too hard. Well, they eat rocks for crying out loud! Anyway, I got some milo and I've had it soaking for two days now. I was thinking I'd try feeding from it tomorrow on day 3. We shall see. I put vinegar in the water and everything and it still is not fermenting that I can tell. So, I will continue to wait. Maybe I'll add more vinegar. I also have a couple heating pads. Maybe I can warm it up a bit. It's been getting colder here at night and I'm thinking that might have something to do with it. I'll put the pads on low and see what happens.
I've been trying to vary their diet a little, so instead of adding all the grains every day, I've gone to adding something different every day. With that in mind, I bought a bag of scratch. It has milo in it. I put it in my regular ff mix which ferments for about 24 hours before feeding out. So, far, I don't see any milo left behind in feed dishes.
Regarding winter feeding... I've been making it in my house and until I get a feet barn built, I'll continue doing it in here. I was thinking that with winter coming and the amount of water in the mix and it gets pretty cold here that I would get a gutter feeder set up and then on the bottom of that gutter, I might run some heat tape like you put on a water pipe or something like that in order to keep it warm.
