We had one Indian Runner Duck egg hatch that some chickens were sitting on (they sit, but they are horrible mothers). Duckling has been in our house since it hatched a week ago. Completely imprinted on humans. We do take it outside to run in the grass for a fee minutes each day and we hold it and give it some cuddle time, but it is a lonely little one. We won't put it out with the ducks (3) and chickens until it has feathers. Do we need to find another duckling to put with it? Will a baby chicken work if we can't find a week old Indian Runner Duck? Don't really want a different breed duck. Thanks!
