No.....If buying from a Hatchery they do it...It has to be done to one day old Chicks...Besides no one will sell you a Single dose of Mereks vaccine...It would cost a fortune to only do a small flock....Only Hatcheries can do it....So I inject the baby chicks myself with the vaccine?
And also what other viruses do we need to worry about. I read of cocci as well which comes from them ingesting dirt?
Cheers!
