Hello there, I have a mallard hen that has successfully hatched a duckling, and it is keeping it in the nest and won't let it out our us see it. I'm concerned it won't be used to people, though we did get to hold it twice or so. It seems okay, but I feel anxious like we should be more consistent. I don't want to force anything and risk the unintentional harm to the baby, or upset the mother. Any advice?
