Strange breathing

[Danel]

Hi all. Can anyone help. One of my ducks is looking terrible, unlike my other ducks who all have healthy looking feathers, bright orange beaks etc. I have separated her from the rest. She is breathing very strangly and wheezing almost. I have started giving her 1ml of colloidal silver (18ppm) heard that helps with any respiratory infections. Any feedback or advice. I have attached video. Unfortunately you can't hear the breathing as she won't let me get closer and don't want to catch her again now and stress her out.

Your video didn't load you need to put it on Vimeo or youtube then copy and paste here.
If you can get the video and pics here hopefully we can help. Is she eating? How old?

O dear. Yes she eats, lays, quacks. She will be a year in December.

Forgot to ask what breed? Has it been extremely hot by you? Has she molted yet this year?

I'm in the southern hemisphere so it is still winter. She is the only duck that is struggling with this issue. All other 19 ducks are 100%. He beak is also much lighter in colour. The other ducks all have bright orange healthy coloured beaks.
