PLEASE CORRECT ME IF I MIS-SPEAK. I am still absorbing this info & things do get jumbled.
Where are our experts when you need them?
Here are the questions if you are willing:
1) Where would you suggest I get the vaccine?

The vaccine is cheap, the needles are cheap, but the stinkin' shipping will get you. You can "split" the vaccine into seperate vials so you don't waste it all. Once the vaccine is mixed, it is only good for 30 minutes or so. Splitting the vaccine (especially for those of us with small hatches) is much more economical. Sommer and I have been timing our hatches so we can meet, have a chick-pokin' party, and be on our merry way. It saves money, time, & worry
Also--the Stockman's on 67th and Buckeye said they would special order it for us, if we were to ask. This might save us on shipping.
2) When can I vaccinate? Is it too late from my 2 week and 5 week olds?
It couldn't hurt. Poking day-olds is hard. They don't have a lot of extra skin. If the younger chicks have been *mostly* quarantined from the rest of the flock, you should still be good. Basically,
any unvaccinated bird is at risk---if only to become a carrier. So vaccinating older birds at least gives their immune system a CHANCE to develop an immunity to the virus. It is a bit of a race: which will win--the vaccine or the virus?
After vaccination, it is IMPERATIVE you quarantine the bird for 2 weeks. Otherwise you set the aforementioned "race" in motion.
3) You don't have to find a vein or anything do you?
Nope. The vaccine is sub-cutaneous. That is: you poke under the skin.
4) My adult hens are 18 weeks old. Do they need vaccinated?
This is where my understanding of the "age immunity" gets fuzzy. The "prime time" for Marek's to pop up is between 16-24 weeks. This is the age group where you will start seeing deaths. Your birds are still at risk. If they have not been exposed to Marek's, vaccinating them now will not hurt them, and will probably protect them. Thi If they HAVE been exposed, the vaccine won't hurt, but it will not help either.
5) Where do you get necropsy done and how much does it cost?
I am still looking for a few places. The U of A will do it for $200, plus the cost of overhight shipping or driving down to hand-deliver the bird. I BELEIVE there is a place downtown, associated with the Arizona Dept of Agriculture...but have not had any solid leads yet. I am still looking. The Emergency/Diseases forum stickies list a few contacts as well--but I do not have any experience with them.
