I am considering adding a compost pile close to my chickens. I've read a lot about letting them forage in it to turn the pile. I also want to add their manure and shavings to the pile. My only concern is in regards to the kitchen scraps I put in. If I put onions and other kitchen scraps that I know are not healthy for chickens, will they just pick around it? I really don't want to have to separate my compost waste! Has anyone had experience with doing this?
