Since you have access to the labs there in Tulare or is it Turlock (can't remember), can you contact them and ask if you could bring by a stool sample for parasite testing and a gram stain? I fear that maybe your hen does have a respiratory infection that has spread to be reproductive tract. I know that vets are expensive, and good ones are hard to find, but I think your hen really should be seen by a vet, and not just a test at the lab, I think this hen needs to make a trip to your closest vet that will look at her. otherwise, I fear prognosis is poor.
