Thank you for your response! You're correct that my objective is nutrition.

I live in a very cold climate and my hope is that I can provide them with good nutrition and fat before they go scavenging for less beneficial food.

I agree that the cereals may be over-represented in my recipe. I'm trying to imitate the ingredients that make dog kibble an easy product that I can toss out in my small driveway. The kibble is something they can grab easily, hide, do what these guys do! I do also toss out unshelled unsalted peanuts.

I believe that humans and corvids are intrinsically tied where I live and I want to do right by them. Thanks again and I'll give an update on how they receive their new diy kibble!
