You can 'start' a pedigree for this buyer--
First- tattoo the kit, and your adults.
Then- Start your pedigree-- Kit's tat number and information where it belongs--
your adults,( it's parents), and their tat numbers in the proper place.
Then, for the kit's grandparents-- Use something like "sellers blue buck and Sellers REW doe .Make this information as accurate as you can---
granted-- not the 'best' pedigree-- but does provide as much information as you can muster up without lying. A pedigree is a record of breeding/lineage-- every animal has a'pedigree'' the only things are-- 1)- is it KNOWN? and 2) is it accurate?
