My state vet is coming out to my house on Tuesday to test all of my chickens so they can be NPIP certified. I am a little nervous about this because I hope none of them have Pullerium (spelling?). The vet says it's rare for one to test positive but still... How many of you have had your flock NPIP certified? Did you have any problems? Also, if I buy any other birds that come from a NPIP certified producer will they still be NPIP certifed when I add them to my flock? I'm getting 15 new chicks from Ideal in February and I'm wondering if that will have any affect on my birds' NPIP certification. I hope that makes sense.
