My almost 4 week old RIRs hate the feeder. The long one with the holes on both sides. I actually think that their heads are getting too big. Am I right on this one? They would rather eat from either my hand, or the feeder without the cover. I dont dare leave the feeder with no cover, as they would scratch it all out. ( Ask me how I know) Suggestions from those who have reared many a chick.
