I asked this question in the chicken area & was asked to move it to duck forum I am new so I was glad to hear there was a duck area as well. I have a couple flocks of chickens & one day I woke up to see with my young hens a duckling. He was not a small duckling but still a duckling. He has purple markings on his wings & I thought he was mallard but he is very small & he is about a year old now he also has no white collar marking. His bill is a tanish brownish color NOT yellow. Any ideas? I saw American Black Duck ? maybe? Roughen? I just saw Mallards & he does not seem to have the popping color his head is greenish but he has brown in his head at the top.
