If your getting your feed/grain from a mill you get Whole Roasted Soybean (WRSB) instead of the Meal.
The WRSB is a little lower in Protein but is much higher in Fat. (I believe it's right around 38% protein and 17% fat). My birds dont eat the meal so well but go nuts over the WRSB.
If you do get some it will have a 'Peanut Butter' smell to dot to the roasting.

Not getting it from a mill. I think what I'm getting is the crap left over after extruding the oil. With only a dozen birds, getting a lot from a mill is out of the question. Some day!
