I personally, don't care about NPIP. With the certification, you are obligated to buy only from NPIP certified hatcheries, etc. and to me, this doesn't seem fair. But I understand the reasoning behind it. I've looked into NPIP here in my state, and am willing to become NPIP certified. I am so willing because it's a safety measure for ME. I have been contemplating on selling hatching eggs on EBay, but I don't know the kind of people that may buy from me. What if someone bought from me and then tries to say that I infected them or their flock with typhoid or avian influenza? What if they try to sue me? At least, if I have an NPIP cert. and I comply with the restrictions of buying only from other NPIP cert breeders, I am keeping myself safe from any legal issues that could arise. Really, I think you are only going to have issues with these diseases if you are a large scale commercial distributor with unsafe and dirty housing conditions. But what if? Better safe than sorry, IMO. Plus, I've got nothing to hide. The cost for me to be NPIP certified is around $25 annually and THEY come to me to test my birds.
