Hi. About 3 weeks ago we got our first two ducklings and two chicks. The ducklings are crested Perkins. I didn't know anything about Crested ducks at the time. One of my girls has started losing balance and flopping on her back. We kept her wrapped in a towel and she seems ok when she is sleeping on my husbands lap. But not so much on her own. I have read quite a few threads and it seems that most non crested ducks with these symptoms toxins or vitamin deficiency the likely culprits but with cresteds neurological issues are suspected. Are there different signs between the neuro issues and vitamin deficiency? What are her chances of making it though this? Any suggestions would be greatly appreciated!
