Can I give the Marek's dz vaccine to 20 week old pullets?

[mfjohnson]

We just went through a difficult 2 week period that claimed the life of one of our girls, a 20 week old EE. She had the classic symptoms of Marek's and it progressed like I feared it would. However, on the bright side, the four others appear to have escaped it, or at least have so far.

I was wondering if it is OK to give the others the subcutaneous vaccine that is for sale from Jeffers? It has it listed for "day old chicks" but I have heard that you can vaccinate older ones. Any thoughts?

Thanks!
Mike
