My chickens love eggs. I'm sure you have some of those around. Fry some up or hard boil. I don't give mine raw. We get so stuck as humans on "balanced diet" that I think sometimes common sense flys out the window. You can feed bird seed, suet, oatmeal, yogurt, left over meat, corn grits, cooked pasta etc. I don't feed spoiled meat or foods I question but pretty much what you eat they can too. They will think they are on holiday with all this tasty food.
