There's a farm in Texas that sells pullets and cockerels. His chicks come from Murray McMurray, who offer the newer vaccination. Shipping is very expensive, since the birds are older. After losing 7 of 9 supposedly vaccinated pullets/cockerels from a local breeder, I bought 9 chicks from MM. Of those, I have 8 healthy pullets and one recovering from Marek's.
If you are interested in the farm in Texas, I can dig up the contact info. I plan to buy a cockerel from him - I think it will cost ~$80 by the time I pay for shipping. Multiple birds would drive the cost down some.
After I have paid for the Marek's vaccine (HVT based, the old one) with shipping and syringes to myself twice over, I probably have over $100 in a single bird just vaccinating myself. $80 sounds like a deal for a sure sexed, healthy, vaccinated bird....
It feels stupid to say that for a hatchery bird, but this disease sure changes how I look at things!!
