Hello. First of all sorry for my bad English.My duck was limping a week ago so i decided to get her to a vet. They told me that nothing is wrong with her and you can take her home but there she had an injection near her leg. A few days later she started behaving abnormal. She was lethargic and she didnt want to eat anything but she was drinking water. I gave her some food wih syringe and the day after she started to eat and drink. But she is not as active as before. Most of the time she is staring at some point while her friends are bathing or eating something. Most of the time when her friends are sleeping she stays awake and doesnt sit. I tried to pour some apple cider vinegar into her water today. Im really worried about her. Do you have any idea what might be wrong with her?
