this happened a few years back, but the recent arrival of 10 new ducklings made me think about it. I got 4 duckling from efowl. they all came in alive, but one the top of his beak was bent upward. He had to breath through his mouth, and had an unquenchable hunger. he lived for about 5 months, but never grew up. while his sisters were mostly feathered out, he still looked the same as the day we got him. he finally drowned when we went on a camping trip. has anyone else had this happen? does anyone know what caused it?
