I have been feeding my ladies just layer feed up til now. I started with oyster shells for a treat. They love that and chase it down as I throw it. This week I mixed in some cracked corn. Well now I'm noticing the layer feed pellets all under the feeder. They didn't do this before. I also sprinkled in some DE for worms. I'll have to test now if it's the corn they want. I'm holding back the feed and letting it run low tomorrow. I don't want to spoil them on something that doesn't have as much nutrition like the corn over the pellets. I have seen this with dogs. Once they get the good stuff they turn their noses up at the other stuff. Does this happen with chickens?
