Download and then fill out the sample submission form. Then download the full DNA-collection instructions and read them through before getting started. Print the DIY blood card sheet: the number of sheets you print depends on how many birds you are testing. Print card sheet on plain-white computer paper.

Gather cut-out DIY blood cards, small plastic bag or paper envelope (one per bird), sanitized nail clippers, rubbing alcohol and cotton ball/swab, and coagulant to clot bleeding from the nail (cornstarch, flour, baking soda, etc.). Collecting DNA is less stressful for your bird when you’re fully prepared.

With the bird restrained, make sure the nail is clean first. Use the nail clippers to clip the bird’s toenail just enough to nick the vein (see full instructions for details). This will produce drops of blood. Place the blood card under the cut nail, allowing the card to absorb enough blood to be visible. Use coagulant on the bird’s nail afterwards, if necessary.

Allow sample to air-dry completely, and place in labeled envelope. Put sample envelope(s), sample-submission form (s), and payment (if you’ve not already paid online or by phone) into a mailing envelope and address it to DDC.
