I haven't written anything on the thread in a long time..hi everyone!
I just wanted to state a word of caution when feeding legumes (beans/peas) raw (including sprouting). Many of the legumes are toxic and can cause health issues over time if they have not been roasted or otherwise cooked. The birds won't choose to eat them if they have a variety of other feed available. But if they are forced with lack of other choice they will.
Here are a couple of links that might be helpful in determining what you want or don't want to feed. (For me, there are some things on these lists that I would never feed my birds under any circumstances...but there is a lot of info worth looking at if you get a chance.)
If you look at the "protein sources" (as well as the grains),
there are some listed that MUST BE ROASTED (heat treated) AND SHOULDN'T BE FED RAW NOT EVEN SPROUTED, SOAKED OR FERMENTED. (2 examples of this are Amaranth and soy beans. Kidney beans are another I believe.)

If you want to get a look at some of the issues with grains and percentages recommended, this is worth reading through
