possible coryza outbreak in my flock

post #1 of 6
Thread Starter 
Hi, I'm ashley. Been following BYC for a while now and it's been very helpful for me. Now I'm stumped. I believe my frizzles are carriers for coryza and my flock has been sick. I recently had to put down a barred rock chic because she was so bad, even though she was quarantined I'm noticing my other barred rock chic's eye is swelling and she's starting to wheeze, my araucana rattles but no facial swelling , I also have a brahma rooster that quit crowing 2 days ago. My frizzles, ameracauna, and rhode islands seem fine. I've been putting oxytetracycline and electrolytes in their water for 3 weeks, changing it daily. As well as medicated food. Araucana showed improvement after 2 weeks of antibiotics but now she's relapsed. I keep the coop clean as well as their food and water. This is my first flock and i have silkie chics waiting to come home. Any suggestions for me? Also, my americauna and araucana are 8 months old and haven't produced any eggs yet. Is it safe to eat their eggs if it is coryza?

Welcome to BYC. MG and coryza both can cause swelling around the eye, and you can't really tell which one for sure without blood or nasal testing. Your state vet also could perform a necropsy to test for it. Coryza generally causes a bad odor around the face. Since both are chronic diseases, they can come back, and sometimes are complicated by secondary infections such as E.coli. Most sick chickens won't drink enough water to get medicated with drugs in the water. Many give Tylan 50 injectable orally or by injection to treat MG.Coryza can be treated with a combo of Tylan 50 and Sulfadimethoxine or Sulmet. Quarantine won't prevent these chickens from being carriers. I would probably call the state vet to check on testing or a necrospy--here is a link for that:

*update*
I gave tylan 200 injections in breast for 2 days, 1 cc for older birds and half that for younger, as well as electrolytes in water for a week. They all slowly regained health. Keeping the coop clean and disinfected, spraying vet rx often and applying it onto birds necks & under wings seemed to help ALOT.

Thanks for the update. Were you able to get any tested to confirm your diagnosis?

No, I spoke with a vet who believed it was severe upper respiratory issue, blocked sinuses. She said it sounded like coryza in the bird I culled. I also vaccinated my flock against fowl pox and will be vaccinating any new birds. Lesson learned.
