The other night DH and I went to a sale and sold some of our chickens. When we got there we were told that our chickens were suppose to be NPIP and we were asked if a few of our birds could be tested for the state. Well we had no clue about NPIP and we allowed the man to test our birds. They all appeared in good health, but now I am worried. First, what is some of the tests come back and something is wrong with these birds? These are birds that we got from other people, will that matter? What will they do to the rest of my flock? Second, is it worth it to get NPIP? We are not regular sellers but do plan on selling eggs and chicks some time. Any feedback would be great!
