I feed all of my birds the Scratch and Peck starter 20% protein, or Grower. Whatever I can source. I bet that you could feed the 20% protein to the meaties. They might grow slightly slower but it would probably be beneficial to them.It is hard to find higher protein (20%+) Scratch and Peck options, but you might consider supplimenting their feed with a measured, SMALL amount of flax seed (not more than 10% by weight) - meaties can take a slightly higher fat diet, since they aren't intended to live long
Flax seed is a good idea too.
