Hello, I'm going to try fermenting the food for my flock of 17 layers. I've seen the recommendation of 1/4 lb of feed per bird per day for dry feed, but how much fermented feed should I expect to feed per day? I'm assuming it'd be a little less, and every flock is different - but is there a rule of thumb I can use as a starting point? Also, for those of you that exclusively feed fermented grains, do you feed it all at once? Twice per day? Some other schedule? THANKS!!
