Hatch and identity records are the foundation
Ask the breeder for written hatch details for your bird: hatch date, species and subspecies if relevant, and sex if it has been determined and how. Many breeders issue a hatch certificate; if yours does not, get the same information in writing on their headed note or receipt. Record the closed ring number exactly as stamped and keep it with the hatch details, because that ring was fitted in the nest and ties the adult bird back to this chick. For a larger parrot that has been microchipped, obtain the chip number and registry paperwork as well, and check the numbers on every document agree before you leave.
Parentage and rearing history explain the bird you take home
Ask what the breeder knows about the parent birds, including their ages, health background, and whether they are related, and write it down while the breeder is in front of you. Then cover how this chick was raised: hand-reared, parent-reared, or a mix, when and how weaning happened, and which foods the chick weaned onto. A bird's confidence with people, its willingness to try new foods, and its early independence all trace back to those weeks. If the chick has seen a vet, ask for the practice name and what was checked, so your own vet can request the note.
The current diet sheet prevents an avoidable setback
Get the present diet in writing, in the breeder's own detail: the staple food as fed now, fresh items the chick accepts, feeding times, and any supplements the breeder uses as part of a normal routine. Take home a supply of the same staple food even if you plan to broaden the diet later, because a newly homed bird that recognises its food eats, and a bird that eats settles. Changing home, people, cage, and diet all in one week is a common reason young birds lose weight and confidence, and the diet sheet is the cheapest protection against it.
Do not leave CITES or sale paperwork behind
For species listed under CITES, the breeder should supply the paperwork that applies to the sale and movement of the bird, and you should check it names the correct species and matches the ring or chip number before money changes hands. Keep the sale receipt with the breeder's full contact details; a good breeder expects to hear how the bird settles and can often advise on the individual chick's habits weeks later. If any document is promised for later posting, note what is owed and when, and follow it up promptly while the sale is fresh for both sides.
Start the bird's lifelong file on day one
These breeder papers are the first pages of a file that may run for decades, through vet changes, house moves, and possibly a future rehome. File them together immediately, add your purchase-day photos and your first vet visit note, and keep the set growing rather than reconstructing it later from memory. Beginning the file in your bird's KinsLe Transferrable Profiles record keeps the breeder's history attached to the bird's profile, so its story transfers intact if the bird ever moves to a new owner.
