Out of 6 ducks, I have three fawn/white females. They all looked the same and had the same posture and then after one had surgery on its foot and was kept away from the others for a while I notice a difference in her posture. She is very vocal, but is also scrunched down all of the time like she doesn't have a neck. Is that because she is low duck of the group. She seems fine besides that. She stays away from the drake who used to pick on her.
