Quote:The mareks should be given first day, vaccine should be no older than one hour after mixed. Some of the other you can double up when they are old enough. Some have to be given individually. I only post this to try and help some of the newer people keep from loosing all their flock. Myself I will not buy an adult or chick unless it has been vaccinated for Mareks. This is certainly an individual decision but please do not take sick fowl to a show and infect everyone else.
