I have three female Pekin ducks in one of them is expressing signs of supplement deficiency I took her to the vet she was given supplements I started giving her supplements at home but now she will not come out of the water for more than 10 minutes and when she does she is hunching her back like she wants to preen her stomach but she falls all over the place, can't keep balance or seem to bend head down to tummy. Does anybody know what's going on doctors have no idea and neither do I but I feel so awful for her that I cannot help her. She's suffering and struggling. I am not an animal killer so please do not tell me to put some soy sauce on her and cook her
