I am currently feeding FF. I am using a high protein layer ration (20% non medicated). I was having a lot of issues with waste of my dry feed that I had out for free choice during the day, between the FF and the dry I go through about 50# every 5-6 days. I got a LOT of wonderful advice from folks on here! I took out the dry and am now feeding smaller portions of the FF, about 4 scoops, maybe 3 cups at the most, 3x's per day and they love it! I add to my layer scratch, a little extra corn and BOSS because its cold here, and some oats and barley. I ferment using Braggs ACV as a good starting agent that helps speed up the process slightly. I'm going to be switching to an all purpose feed with a lower protein content in a couple of days, again non medicated, that has most everything grown here in Alaska and add a brewers yeast and kelp powder to the mix to make sure the vitamins and minerals are sufficient for my birds. Once I switch to AP feed, that will cut my commercial feed use almost in half while still providing sufficient nutrients for my flock. Knowing how to calculate crude proteins of multiple ingredients together as with the other nutrients is rather difficult but can be done but it all needs to be balanced. That's why I am still using commercial feed, just going smaller scale with it, and you WILL save money with this route!
