That's funny. I just made up a big batch of sprouts and gave some out yesterday and today. They looked at it and looked at me. Doing a staredown. So I gave them their FF. They eventually ate both but I thought they'd go crazy for the sprouts. They don't free range and I do add alfalfa pellets, not a lot, to the mix. Maybe 2-3 cups to the 5 gallon bucket. That seems to really beef up their eating. Only trouble is, it's GMO.When you say fermented feed, do you mean store-bought pellets/crumbles or seeds, corn, etc? I don't ferment their crumbles. I just mix them in with the seeds and scratch when I feed them. On fodder...I used to feed them sprouted seeds, but they don't seem to like it as much now given the fermented option. I'm guessing that could change once winter really hits.
How long have you been feeding them fermented? They may just need to get used to it!
