Is mixed bird seed okay to use as a base to make my own scratch? They seem to have lots of the same ingredients. I add dried mealworms, hemp seeds, instant oats, raisins and more cracked corn, but need to increase their protein for a short time due to aggression bordering on cannibalism. I have four Barred Rock sisters, about 6 months old. One all of a sudden began pecking sister's head and drew blood causing a frenzy! Separated the b*tchy pecker out, she'll have to earn her way back to the top. Sister is healing but so shy now. Most info I read said to add more protein to their diet, among a HUGE range of other things like boredom, more greens, bigger space, need salt, lack salt, need vinegar in water, etc. Most of which didn't apply to them. Hopefully they will be one day be a happy sister flock again. :/
