I understand that, but our girls were fine on this food, and cleaning it all up until about 2-3 months ago, and even with new bags. Eating the pellets/crumb and anything else included in it. Maybe the recipe changed or they're having some manufacturing issues; it was about the same time we bought some wheat from the same country that weirdly contained buckwheat, barley, peas that were not on the label.I really believe the only way to be sure they get a balanced diet is to keep before them at all times a commercially formulated pellet or crumble. If they can see individual components like corn, peas, wheat, etc., they will surely pick out what they like and leave the rest. The same way one of my kids picks peas out of a stew or pot pie and won't eat them, lol, and the other one picks olives and onions off a pizza (he now gets cheese only). The items you are feeding your chickens should only be offered as a treat, like cake and ice cream, not a steady diet, IMO, and should only consist of about 10% of their diet. I'm not an expert in nutrition though, and I can't remember who is. Hopefully one of our experts will chime in and advise you.
