This hen has been sick for a while, when I got her as a recuse hen a year ago , she was ill with swollen face etc but was able to treat her to antibiotics, she then developed a funny hiccup sound around 6 months ago , as she had no other signs of being ill I thought it was just a funny noise she made at me, but around 3-4 weeks ago she started a moult and has gone very down hill iv separated her , she is eating but losing weight she stands with her head up breathing very bad it's very bubbly sounding, her comb went very pale but now turning a bit purple in colour. So far iv giving her a garlic mix , orangano tea, ACV , life guard , I'm not able to get antibiotics. I'm about to worm her. But she has had DE powder. I'm not sure what illness she could have, am I being cruel keeping her alive? Her poop is normal but very small . I'm out of ideas on how to treat her.
