My chickens have just stared at almost everything I have tried to feed them. The only things they have eaten were raw oatmeal (didn't touch cooked oatmeal). They also love to eat the wild clover that grows in their run. I have tried feeding broccoli, arugula, scrambled eggs, yogurt, and grapes but they dont eat it. I'm thinking they don't know it is food so they do not eat it. What do you guys do to get them to eat new foods?
