No it’s not all sunflower seed. It’s a mix of layer pellets, feather fixer, cracked corn, sunflower seeds and oats that I give a cup pre hen/day. I don’t have the meal worms mixed in with what I spread out. I give about a 1/4 of meal worms pre hen/day. My girls don’t get as much free range though, at the moment our neighbors have seen a young mountain lion and we had a bear attack a dog not far from us, so I keep them pretty close. I live in the San Luis Valley.
San Luis Valley...as the crow flies, we're probably not that far apart. But those darn mountains make it a half day drive.
