I have a 2 week old pekin duck that my fiance and I hatched from our older pekin's. The duckling had no issues until this morning when I noticed it's neck was turned like it's always looking up and it is having trouble with balance. Everything I've read says wry neck. We are using chick starter feed which is not enough niacin which we did not know until today. I read that you can use enfamil poly-vi-sol vitamin drops, has anyone had success with these? I ordered nutri-dent for poultry as well but it will take a few days and all the stores were sold out. If anyone has successfully treated wry neck how long does improvement in symptoms take and is it fatal? My duckling is still eating and drinking but it's balance is off.
