Oh, dear. You're lucky you have a vet that can help you. You probably already know you can get vaccines through firststatevetsupply. When our chickens went through the double wammy of ILT and Avian TB, I had some doubts about some of the diagnoseses that they did during the necropsy. But the State vets here were very good and answered a lot of questions. We were under quarantine, so they had to. But, a few times I got the distinct impression that I knew more answers they did. fyi I also called the vaccine manufacturer; they got their vet on the phone for me and she answered the billion questions I had about the vaccine, and the diseases. They were very sympathetic and a wealth of information. Carrie, I'm so sorry for you; I know how you must be feeling...but, just remember this...chickens can be very resilient and resistent, and our flock sure demonstrated that to us. I was so afraid we would lose them all, but we actually only lost a few..four or five, as I remember, to both diseases. Though that was painful enough, it could've been a lot worse. We prayed a lot and I think our prayers were answered.
