Because of the AI requirement. VA is one of the few states that require it. The AI testing requires lab tests on swabs from a number of birds in the flock. Also it has to be done every 6 months.
NPIP is once a year and is subsidized in most places that require it. Also shipper must get a permit from the state of VA to ship there.
So if I became NPIP and I order chicks from an NPIP farm, would all the permits still have to be in place? Sorry for all the questions
