Hi all, I'm new to all this so need as much help as possible. I have just acquired some white ducks (not sure of the breed) They belonged to someone who I know and they were kept in very poor conditions with dirty water, no clean bedding and very little food. I have noticed that one duck seems to be making a noise, not quacking but wheezing, when she breathes and her tail is bobbing up and down. She also seems to be panting, and her bottom is not as clean as the other two. I am really worried about her, is there anyone who can offer any advice on what this could be and how to treat it, or do I need the vet and is there a chance she needs to be put to sleep? I've only had them 5 days and I'm already very attached to them, please help!! Thanks Claire. xx P.s I also have 4 chickens who are sharing the pen but seem very happy and healthy.
