I finally got the necropsy results back from UConn and the two little birds that died had what looks like Mareks. So, what do I do?...Ive been reading and reading and it appears to me that all chickens have this in some latent form and that it can come up during stress or...? And also that 5% of vaccinated chicks are not really safe, and thats IF they handle the vaccine correctly./ I have a number of chickens that are definitely immune and it seems like its only struck a few hybrid young birds (showgirls and frizzles) tho quite a few of those are OK. If I put down my entire flock and started over I could easily have a reinfection in that the vaccine isnt 100%... I do have 2 turkeys with my flock now and supposedly that will give some immunity to the newer birds, because they have to pick it up early in life. But otherwise, I am getting alot of conflicting information. The "doc" on first state vet supply says that you can vaccinate older birds and sick birds...that it may work...but having live virus around is a big no-no if you order vaccinated chicks...so whats up with that advice..."doc" is not a real Dr, and it seems like if the idea with vaccinated chicks is that you only get them if you can keep them totally separate from your unvaccinated birds for 10-15 days lest they infect them.... I need some advice. I have 2 runner ducks who seem just fine, 2 heritage turkeys who seem just fine, and 25 4-5 wk old americuana chicks in the basement who have been in the same room with dust and shoes that were around the sick birds. I have my original flock and all of the birds, my original roo, some young birds from this year, and new chicks hatched by broody moms, etc...are fine. Ive just lost a few birds all of the same age and strain of hybrid silky/showgirl/sizzle line....the few birds who have gotten sick and died were spaced out over the past months of the late summer into fall. I also lost a turken but she seems to have had some sort of obesity problem that is not really diagnosed in the necropsy. I have a marans with bumblefoot and very liquid diarrhea in the basement and have wormed and treated everyone for cocci for a few weeks because of cecal orange material in their poo and also because the UConn tech reports round worm nematodes in the intestines...but not anything highly out of the ordinary or that would kill the chickens. I have not seen any huge die off or shedding and I hope that the infestation was small enough that its just been absorbed and is gone. It is possible that the amt of worms seen in these birds was enough for a delicate breed to get stressed enough to bring on the mareks that is dormant. So I used corrid for a couple of weeks and then off....I used eprinex pour on and then took a week rest...now I used sulmet and everyone's poo looks OK except for some Barnesvelders who perch in one spot and are pooing some orange material still...and some normal poo, so it could be that the sulmet was a little strong for their symptoms and that will get better. I used eprinex on the young chicks in the basement just in case and 24 hours of sulmet just in case...and the same on the ill marans. I have one showgirl roo who is outside in a dog house who has the neuro disease which is probably mareks. I had to put his sister down a few days ago as she got much worse and her quality of life went to zero. he seems better and is eating and drinking voraciously, etc...he just has a bit of parkinsonian shaking in his legs and cant walk. he sort of scoots around but stays in this doghouse. The dust has already gotten on all of my other chickens, so Im not too worried about infecting anyone. Id love any suggestions....everyone has a different take on this ...what do I do??
