So, I have two Cayuga ducklings. One of them (Daffy) always had a problem with walking. My other duckling (Sue) is perfectly healthy and eats good and is twice the size of Daffy. Recently I thought Daffy was really sick. I took Daffy to a vet, and after the her examination he told me that she has a neurological issue that is affecting her development. He told me that she is lucky to have me and that she would have never survived living in a big flock or in the wild. Anyway, Sue has been walking like her. Not all the time, just once in awhile. Do ducklings ever imitate each other? Maybe Sue thinks she is the one who is walking wrong and is trying to walk like Daffy. Any suggestions or advice anyone can give?
