I am interested in only adding a couple new chickens (will get baby chicks) and am considering getting them from one of our local farm stores. I called the stores and asked if their chicks are Marek's vaccinated. None of them had any clue of what I was talking about. All of the people I spoke to finally said that they don't think any of their chicks are vaccinated. One store said they are checked for typhoid (?) or maybe TB. My chickens I currently have were all Marek's vaccinated from where I got them (mypetchicken). I really don't want to order on line again, cause I only want a couple chickens and also do not want to have to pay the shipping fees. I don't know about Marek's, what it is, how dangerous it is, and how likely chicks are to have it or get it. How important is it to have chicks vaccinated for it?
