Disease testing is not all the NPIP programs do. They encourage safe management that will prevent other diseases from coming in. Yes, it's no cover all, but I believe it to be beneficial. Maybe you have that down already, but many folks don't and it's a good way to spread that knowledge.
You...
If my understanding is correct, the testing is all that is required for selling birds within state borders. If you want to sell elsewhere you might have to go full NPIP.
Not entirely sure---US rules are weird. :hu
They shouldn't have any housing requirements, then... also, if you go full NPIP you might be able to pay for getting ducks tested rather than having to separate... don't know Texas rules, all I have is information from people in other states.
Is it just AI/PT or is it full NPIP certification?
If it's full NPIP they might also not allow you to free range, don't know if that would be an issue...
