Mine eat EVERYTHING! I do give potato peals after baking/boiling (I know - I'm pathetic) because I read that cooking makes them safe and they love them. In all honesty I'm trying to accumulate a compost pile in a corner of the run but it's not working. They eat it all. I'm reading Harvey Ussery's book- it's wonderful - got it for Christmas! I plan to try his suggestions for composting for my garden. Then again, his book gives many ideas for letting chickens do the work as far as creating and working the compost.
