Homemade chicken and duck feed duck feed together?

[farmerbrowne]

Tough one here,
I have been mixing my own feed feed for the chickens for the past 6 years. Now I just recived four muscovy ducks. Instead of trying to have two separate feeds I was wondering if there is a better mix I could make up. I had watched a video about this gentlmen claiming that chickens will just "crap out" the extra protien. his mix has been 2 buckets wheat, corn, milo and 3.5 buckets soy meal. Does this make sense? Will chickens be ok with the 20% protein level?

Chickens are fine with 20%, especially if you give them other extra stuff.
