I have recently rescued (because one was unwanted do to his problem) these two peking ducklings from a tractor supply. One of them has a crooked neck. He's able to eat, drink and do everything it seems completely normal for the most part. He does get spinning every once in awhile and his little friend helps him straighten back out if I am not there to do it. Also when he grooms himself he is able to staighten his neck and bend it the other way.. as well as move it in any direction he chooses when he is trying to get something. We are supplementing him with vitamin E at the moment because we heard it could be a vitamin E deficiency? Anyone have any experience with this? We would like him to have the most comfortable life possible. Bentley is the one with the crooked neck and Petri and is the other. We are feeding a non medicated chick formula at the moment but have Mazuri Waterfowl Starter on the way! Thank you in advance!
