I have heard that you can possibly introduce chicks into the hen house if you can get one of the chickens to "adopt" the chick - preferably by popping it under her on the nest. Would the same work for a duckling? What's the best way to add 1 duckling (Khaki Campbell) to the henhouse? I will have 2 adult hens in the spring, a couple chicks, and the duckling. Thanks for any advice!
