Well, ever since I started throwing a scoop of birdseed into the run every day to keep the chickens busy, they are scarfing it all down and ignoring their layer pellets. The birdseed is okay nutritionally (millet, small sunflower seeds, cracked corn, milo, plus calcium carbonate) but not nutritionally balanced. Although they also get kitchen scraps and weekly treats of fishfood flakes (for protein) I really want my birds to eat their pellets. They used to eat it fine before I spoiled them with the scratch. How can I "wean" them off birdseed and back to their Blue Seal feed, without depriving them of scratch altogether?
