everyone who sells out of their state has to be tested, to ship or cross state lines, LEGALLY.
As for the chick /egg deal, no they personally arent tested, but their parents have to be, any chick 4 months old or older does have to be personally tested.
As for getting birds, if you are NPIP certified, you MUST buy from NPIP certified seller, period.. if you dont, you will loose your certification.
Your farm also has to be quarantined from visitors. As for the keep them at your moms deal, that dont float. Biosecurity is the goal of the NPIP, if they find out you are doing that, they will revoke your certification. as I said, you have to buy from NPIP breeder to avoid all this, and they MUST give you a copy of the NPIP transfer forms to accompany them.
The NPIP have been around for a long time, there are tons of legal breeders out there who can assist you. There are a number of threads and stickys on here with NPIP certified breeders and list of what they sell.
Now if you dont plan to ship out of state, just sell locally inside your state line, your arent required to have the NPIP testing, you may need state permits though, all depends on your state laws. However, it is illegal if you get caught shipping without it. As for buying, persoanlly, you dont have to have a thing, all this lies as the breeder/seller responsibilty. So buy up what you want first before getting certified, because after that, everything you get MUST come from fellow certified breeders. Yes, they will find out, they test annually, and keep records of each breed, species, color, males, females, etc that you have. If on their next visit, you have a bunch of stuff you did previously have, and have no transfer papers for them, you will get in trouble. In addition, by being certified, you are also allowing them to do random, pop in checks on you and your flock...
In addition, check with your own state, some states do require, avian influenza testing, macro plasma test, vet health certificates, etc in addition to the normal pullorum/typhoid testing, also over half the states require breeders to have a state import license for that state to ship into it even if you have the NPIP certifications.
I will be glad to give you a full list of what your state requires if you like, had my NPIP agents send me a complete list of each states requirements, you wouldnt believe how long it is!
As for the website/domain name. There are lots of hosting site that you can build your own off of, most are simple to use. Some are free (but cheap site) some you pay for but you get much better sites out of them, build them yourself, all your stuff will be copy right protected, yes your name too. Meaning if you say put like I did, Boggy Bottom Bantams as your name, it is checked against all other registered names, if no one has it, you are good to go, then it is you protected copy righted name, no one else can legally use it then.
One of the most popular hosting sites, if you've ever watched much TV you've seen their ads, It's GoDaddy.com...they are the ones we use. Pretty cheap, and great , and easy to build a site off of. I'm computer stupid, but I did it!
