I mix up a 5 gallon bucket 2/3 full. I use a qt scoop and do 2 scoops scratch, 1 scoop of gamebird, 2 scoops of starter or layer and 1/2 scoop BOSS. Just start it by filling bucket 1/2 full of water. Some ACV and start scooping all the stuff in. I don't put meat or worms in it. You can add it to the finished product at feeding. You may have to add more water. I let mine get to the consistancy of thick oatmeal. Partially cover it so some air can get in. Stir daily for 3 or 4 days. When it starts bubbling or smells like pickles then it's done. Peas and Boss May float but your going to be stirring daily. It all get's mixed in. One bag of gamebird is 26% and costs me $18. But it bumps my protein overall up and 1 qt per 5 gallon bucket will feed 15 almost POL birds for 4 days or more. Worth it.
