These three ducks are a male and two females. They are hilarious, but I haven't noticed them running for feed. We feed regular organic laying feed and they have been laying. We just have chicken feed available. What are some treats ducks like and is there any definciency in the chicken laying food that I should go out of my way for these ducks. They are black with a green shimmer on their neck and heads. We really like them and want them to stay healthy and be happy.
