They print the shipping ticket before they are actually sent out, unless they were sent yesterday.. they go to their local post office around 4 pm in most cases, it'd be worth trying.According to my tracking they shipped out today. If it were you, would you get whatever it takes to vaccinate these birds for Marek's especially since the other one's I am getting are already vaccinated for it? Where do I get that vaccine? How is it administered?
No, I wouldn't vaccinate myself, by the time they arrive it's too late to be considered effective.. plus add the human error factor. I would keep them as is and see what happens. Marek's don't scare me, and despite my state poultry vet saying it is ubiquitous.. plenty of folks never see or experience it.
