I didnt read up on this Nais yet, but from the perspective of a former resident of massachusetts where i was subject to all manner of census type questionaires and standardized test and the sort, just fill it out and send it back. it doesn't matter how you fill it out, cause they are never gonna come audit your farm to make sure you have the animals you claim or have what you didnt claim.
The one truely wonderful thing about beurocracy is that you can count on them to never do anything significant with the information they gather.
Just make sure you circle NO when they ask if you beat your animals. That sort of thing might raise an eyebrow.
