It is difficult to find a high quality Grower with 18-20 percent protein, animal proteins included, and a full slate of good nutrition. Those fortunate to be in the distribution area of Flint River Mills in the southeast US have some excellent choices. Show Gold for show birds.
Working with your local feed mill is sometimes challenging as they tend to fomulate their feeds for the commercial flocks in the area, either layer houses a mile long or feeds designed for the broiler birds. Our birds are basically a blip on the radar comparatively.
I always check the GameBird feeds. Often, they have better nutrition than the retail products typically sold at rural lifestyle stores. I don't recommend DuMor feeds at Tractor Supply, and realizing they have several mill/packers throughout the country, but the DuMor 20% Chick/GameBird Starter/Grower here has animal protein is isn't a horrible choice if other products cannot be found.
