This will be the paperwork that is filled out... So every bird entering a public swap gets a tiny drop of blood drawn and mixed with a drop of antigen for testing. The numbered band is on there to prove that it was that particular bird and breed on the paperwork filed. It can be done in advance and sometimes there is a testor present that will charge a fee for doing this. If not, you'll have to check with the MPTL for a certified testor in your area. I believe this paperwork is good for 90 days, so you don't have to have them retested in that time frame if you have multiple venues. Now also note, there are 3 boxes...1 is for our annual breeder flock test, 1 is for just sale birds, and 3rd is for exhibition. So like in fall if you are showing and want to bring along a few extras to sell, you have 2 separate slips.
