Bread -- yes. Dog treats -- yes. Bird feed -- no. I've put some spent grain out near my bird feeders. Never saw a bird or squirrel touch it. (And there were lots of both out there daily.) After several months, I had to clean it up & put it on the compost pile.
But I always save some in small ziplocs for making bread. And I make dog treats every second or third batch of homebrew.
