I've been really worried about one of my Rhode Island Red hens. She is about 2 1/2 years old, and hasn't laid in around 2 months (which is really unusual for her, as she was my best layer and gave me huge eggs nearly every day). I could tell she wasn't egg-bound because I didn't see evidence of a prolapse and she didn't act as if she had an infection. At this point I was almost sure she was laying internally. Before she stopped laying, she began to lay very unusually shaped, smaller eggs. Today I managed to get a good look at her abdomen. It was distended, and the skin was very red, quite like the internal layers I've seen here on the BYC forums. Her abdomen is hard, not squishy. Does this sound like classic egg-yolk peritonitis? As of late she has also developed a slight wheezing when she breathes. She has no bubbly eyes, no coughing, no sneezing, and no swollen eyelids, just a whistling, wheezing noise. Her crown has also become a darker, purple-red and appears to have shrunken slightly. I knew when I got Rhode Island Reds that I would have to deal with internal laying sooner or later, but I was really hoping I wouldn't have to deal with it in such a young hen. The worst part is that the avian vets around here are very expensive, and I don't know if they could do anything for her even if I brought her in at this point. So now comes my questions: what should I treat her with? I feel like I'm at a cross-roads here. I know penicillin has helped other hens with egg-yolk peritonitis, but I was hoping to treat her with Tylan for her respiratory issues. I'm really scared that if I use both, I'll end up breeding some antibiotic-resistant bacteria in my flock. If I treated her with penicillin, would this get rid of the respiratory problem, too? Thank you for any help you can give--this is one of my gentler hens and I would hate to lose her without exhausting all other options.
