Normally i give my chickens wild bird feed as a snack but i couldn't get any this time. So i got them some " Universal Blend Nutrient rich food for small birds like canary's, parakeets, etc.) They seem to really like it as a treat and it says that its good for plumage and health. This would be ok to feed to chickens as a treat right? Its for small birds so i don't know how it could be dangerous, but i thought i'd still ask.
