hello, I have a 31/2 year old Australorp, Sophie, who does not seems to be doing well. We noticed yesterday afternoon. Her crop is empty so I don’t think she’s eating. She doesn’t seem to want water either. She sounds like she’s wheezing/snoring when she breathes. It gets progressively worse and then she sneezes and seems better. Her poop is a bit mucousy. I have removed her from the flock, though I’m worried that is more stressful for her, I’ve put her where she can see them. The others all seem fine. Her comb is a little pale but not white. None of the flock have layed any eggs which is really bizarre (unless they’ve taken to eating them). I’m planning to bring her to the vet, but any advice? If she needs antibiotics do I give them to the entire flock? Anyone had a girl recover?
