Hi to all! Three days ago I revaccinated against Infectious Bronchitis my two months old pullets, mainly production reds and Turkens...et voilą! Today my favourite pullet, Maia, stated to sneeze & cough! mad ! I've read on Marck's manual that some attenuated vaccines "can cause a mild form of infection" but how mild is mild? Should I consider her ill? She was perfectly healty before! Will she lay wrinkled eggs and start raling at winter? Does anyone noticed something similar after vaccination?
Thanks a lot to you all!
