Since I don't ferment my quail feed longer than 24 hours like one would for chickens I've never had it gone wrong. When I first started using fermented feed for my quail I was fermenting for a few days like I do for my chickens. They didn't like it, and the longer if fermented the more they hated it and would waste it. By only doing the 24 hour soak they are still getting the benefit of soaked seed but none of the sourness that they don't like (and chickens love!) Quail are not chickens, I would not try fermenting it longer again. When I'm done feeding it in the morning I get the next day's feed on to soak. It's plenty of time for quail. I've also tried it wetter and drier but a 50-50% ratio of dry feed to water seems to work the best for quail. I think I'll start a thread about this. I know there are others out there that do this for their quail, and others might want to try it.
