Hello, Some of my flock are carriers of coryza. I thought that it was MG because it comes along with the wild turkeys that keep showing up, but I've recently confirmed it isn't MG. After research I found a vaccine for coryza. I purchased it off the internet, and gave it to all my youngster birds before integrating them into the new flock. So far, none of them have came down with coryza even with the wild turkeys constantly coming around. What I'm wondering is if the vaccine makes my chickens a carrier of coryza. I don't want to sell any of the babies or anything if this were the case. I'd cull all my birds, but I really want them to be able to free range and enjoy chicken life. With the turkeys around it doesn't seem like this is something that can be done without a vaccine or without letting them suffer from coryza. The vaccine is a dead strain, if that matters. Any help is greatly appreciated. I've read all over the place without any actual answers to this question!
