I haven't, would it be tough on her to worm her now?
It might be hard to worm her now when she needs antibiotics. After that she'll need probiotics and then worm. But worms could be contributing to her respiratory distress and sapping all her energy so (head spin) tough call. Dusting her for external parasites with sevin is good except for the dust, maybe a spray? Make sure she doesn't breathe either one. You said she misses food she tries to peck at. It is possible that she is blind at least in one eye (most likely the right) or has very low vision as a result of illness/malabsorbtion.(sp?) This may explain why she doesn't move much or eat unless the bowl is right in front of her. It's pretty easy to check, if you can come from behind and actually touch the chicken's eye, it is blind. I am so sorry your girl feels so bad
