I am working on getting my NPIP Certification as well. Currently waiting to see what the outcome is from the recent decision by the Dept. of Ag as to what they are going to charge us for testing.
I already participate in the Avian Influenza testing program and hope to be NPIP Certified soon.
Btw, I just noticed that no one answered your question about a Welsummer Breeders Club. To my knowledge the only Welsummer Club is in the UK. I've thought about seeing what I can do to get one started but I just have way too much on my plate right now to commit to anything else. If anyone hears of anyone starting something up, let me know and I'll sure help out however I can.
God Bless,
