We have an Indian Runner duck that became broody a couple of weeks ago. I tried to get her off the nest for a couple of days but she refused to move and kept biting at me. I know that all of our duck eggs are infertile right now but there are a couple of chicken eggs (which probably are fertile) she has been sitting on. Since she really acts like she wants to be a mom, we decided to let her sit and see what happens. We blocked her off an area so the rest of the flock leaves her alone. Has anyone else had experience or success with a duck raising chicks? Is there anything I need to be made aware of before they hatch? Thanks.
