Hello - I'm new, but have read a lot of posts since getting my chickens 5 months ago. My question is about cracked corn (and also scatch grains with cracked corn): 2 different bags from 2 different sources have had powdery white spots on the inside of the feed bags. I have asked both sources if this is normal and no one seems to have any idea if it is or not. The spots wipe off and overall I know that cracked corn is dusty. I probably have never noticed this before because I never inspected the stuff I use to feed the wild birds so closely. But, wanting to be safe, I thought I would ask. My concern is that it could be mildew or something like that and all the feeds warn not to feed "spoiled or moldy feed". The corn / scratch itself looks and smells fine, no moisture or clumping. Has anyone else noticed powdery white spots on the inside of their cracked corn? Is is normal? Should I feed it or return it? Thanks!
