i'm posting an update here, mainly because i am so frustrated and need to vent. Penny was on Trimeth/Sulfa Suspension and then Vetisulid Powder in her water when i could not get the syringe of meds down her throat. She was on these sulpha meds for almost three weeks. The vet did a recheck, and i felt confident that everything would be okay, as she was healthy, happy, eating, being a chicken, with no signs of any distress (which she was before the meds also). Well, the new culture showed the e-coli was totally gone (how do they do that in a chicken?) but she was still showing proteus mirabilis, although it was reduced by 50%. The actual counts had been 4+ each, then down to 2+ on the proteus, not that i know what that means. So now my vet wants to put her on Baytril for three weeks (!).
Being concerned about subjecting Penny to another round of antibiotics, i said i wanted to get a second opinion. Found another avian vet who has treated chickens and asked my vet to fax over the labs. When i went to the appointment yesterday, the vet i was supposed to see did not keep the appointment. They sent in another vet who came in carrying some big book of poultry medicine. (i suspect the other vet did not want to contradict the first vet, as they do know each other, as i found out later.) So this newbie vet does a physical exam and makes a lot of remarks in the vein of "not sure if this is normal for a chicken". She spends time referencing her book and leaving the exam room (probably to consult with the vet i should have been seeing). She finally recommends the Baytril for two weeks, even though she is unable to answer the issue of whether or not this proteus mirabilis is even a problem. And actually the only place on the web i could find any information about it that i could understand was Wikipedia which specifically states that it is not pathogenic in chickens.
So here i am, stumped. My gut tells me not to put Penny on the medication. i don't have a lot of confidence in the first vet and have NO confidence in the second one. i don't want to spend another $100 to go to another vet who doesn't know about chickens. i don't want to just find someone who tells me what i want to hear. i really want an answer. All i can think of at this point is to write to a veterinary school that specializes in poultry and ask them to interpret the labs and tell me if i should be concerned. Does anyone know of such a place? Or does anyone have any recommendations of where to write?
Through this all, Penny is acting perfectly healthy. And had i never taken her in for a routine exam, we would not be going through all this frustration.
