One word..... Quarantine!
This bird has come from a breeder(as oppose to a hatchery), is at a vulnerable age and will have been stressed by 48hr delivery. Keeping him isolated from your girls for at least a couple of weeks would be very wise regardless of breeders certification. Marek's disease is widespread amongst many flocks and not covered by NPIP and not treatable once you have it, so, far better to be safe and make sure he is isolated from your girls for a few weeks than be sorry.... I speak from experience!
Electrolytes and a good vitamin supplement will be beneficial and maybe a probiotic. Not sure what you feed your existing flock but if they are on layer feed then switching to an all flock will be better, particularly if you are planning to breed in the future.
I hope he arrives safely. Good luck with him.
