I have a 6 day old duckling that has a swollen neck...low down on the neck, on one side. It's soft and squishy and I wasn wondering if it could be a bug bite? It's not as active as it has been for the last few days since they arrived, but still drinking. They're out in the run (covered) so it's possible that it got into it with a bug of some sort. None of the other 26 ducklings have any swelling. I also posted in the emergency section but haven't heard anything yet.
