We have a pet hen (BokBok) who has had rattly breathing for a long time. We also had another hen with this condition but she seemed to have cleared up on her own. Several months ago, we had a couple of hens with Avian TB. Both died in about nine months. At the time we sterilized as much as possible, to try to prevent spreading. There is no cure for this, and it takes a long time to develop to a point where it is fatal. Not all chickens in the flock will get it. We have been trying to avoid thinking about the possiblity that this is what BokBok has. Unlike our other hens who died, this is her only symptom. We have had her confined for about ten days and on an Terramycin 4 tsp per gallon. This seems to have helped a little bit, but not much. Anybody have ideas...should we try VetRX, or that cough syrup stuff (Spotted Crow, what's the dose you use?) or something else to help her breathing, and where can we get it? She is not laying either, but there could be a lot of reasons why not. She is very unhappy about being confined. If you put em on cough syrup or vetRX, in the event she does start laying, I'm guessing you would not eat the eggs? Or does it matter?
