I have been reading about acorns being used to supplement feed. of course you cant just throw to them, you have to prepare them. per ounce they have 1.7gs of protein, they have fats, magnesium, potassium, calcium, iron, vitamin b etc..[/QUOTE]
Don't want to highjack the thread, but I made acorn flour once and baked some cornbread with it just to add to my list of 'what can I do if i just HAD to do it' stuff. It's a tedious pain and tastes pretty bad, but it's doable. I imagine the birds may like it way more than we did.
