It's been a week or so since I sent a 4-month-old Brahma pullet that suddenly died, in for a necropsy. The vet at the dept. of ag called me today and confirmed that she died of kidney issues and an infection: Mycoplasma gallisepticum So, my flock has been put under quarantine for 45 days and I'm looking for a water soluble antibiotic as we speak (tetracycline). I have not noticed ANY signs from any of my birds. The only thing I've noticed is the occasional sneeze from just about all 20+ birds in my flock. There's no raspy breathing, swollen eyes, or inflammation whatsoever. I last introduced new chicks to my flock from a local auction about 2-3 months ago that still seem perfectly healthy. I understand that I have two options: cull or close the flock. Which is best? I wanted to raise and sell chicks but I can't with MG. My 2-year-old would be devastated without her chickens... I'm at a total loss. I asked if the vet could test all my birds but evidentially that isn't a service offered. So, I know that the surviving birds could be carriers but I was told that after 45 days that it COULD be possible for me to sell/breed again if no other birds show signs of illness.
