Hi everyone! I have a flock of 13 Buff Orpingtons. The flock feeds free choice from a 10 pound hanging feeder in their pen. I normally feed them organic layer pellets from Modesto Milling. In addition, they get a small amount of scratch feed from a hanging scatter feeder twice a day. The 10 pound feeder normally lasts them 5 days. I recently changed their feed to an organic whole grain layer feed also from Modesto Milling and eliminated the scratch feed. Now the flock mines through the feed and empties their feeder in less than 2 days. They leave behind a pile of peas and pellets. I leave the feeder empty for a day and they'll finish off the remaining peas and pellets. I am now having to refill their feeder every 3 days. Are they over eating? Should I be feeding them daily rations instead? Any help is appreciated.
