I dont know about chufa - I have hogs on my place and impossible to grow. My turkeys like wheat shoots and wheat seed. They also like clover. I plant a combination of wheat and a perennial white clover. I dont like rye because it gets so tall my turkeys quit using the plot. I also like a lower growing clover. Browntop millet makes a great summer annual crop for hens with broods - for both the seed and a great bugging area.
