while I was doing my morning chores, I heard the sound of a baby chicken that seamed lost. I have free range hens that have been laying in Muscovy nest, and since the chicks hatch out two weeks before the ducklings, the chicks wander off. I kept following the sound, and finally found it coming from the top rail of a 6 foot high chain link fence. It was a mocking bird! May be that is why I could not locate the baby duckling I heard a while back.
