If you mix --
25 lbs catfish food (32% pro)
50 lbs cracked corn (8.5% pro)
You would get a feed at 16.3% protein.
If I could add a suggestion,
Since you live in Alliance go to Schott feed on East Patterson Street and get a bag of pigeon feed with corn, floating catfish pellet and a bag of cracked corn.
Mix it at --
45 lbs cracked corn
30 lbs pigeon feed
25 lbs catfish pellet
To only other suggestion I have is to see if Schott feed has a non-medicated turkey starter in stock and replace the catfish pellet with the turkey starter.
If the turkey starter is a little less protein you can adjust the feed as needed.
Oh and stay away from the TSC there on State street, there over priced.
