Collection & Mailing Instructions

Read this page before you collect anything. Each bird needs its own dried blood spot, its own bag, and the exact Bird ID you typed when you registered.

Hobby Hen Farms: collecting a blood sample for DNA sexing, toenail method, nine illustrated steps

Materials needed

  • Toenail clippers or small nail trimmers
  • Coffee filter cut into small pieces, about 2 to 3 cm (1 inch)
  • Small resealable plastic bags (zipper bags), one per bird
  • Permanent pen or marker
  • Paper for the ID, with the bird’s name or ID
  • Styptic powder or plain corn starch to stop bleeding
  • Hand sanitizer or soap and water
  • Clean paper towels (optional)

The nine steps

  1. Prepare and sanitize. Wash or sanitize your hands. Gather all materials and make sure your clippers are clean and disinfected.
  2. Restrain the chicken. Hold the bird securely and comfortably. Gently extend one toe.
  3. Clip the toenail. Clip just the very tip of the toenail, about 1 to 2 mm. A couple of drops of blood will appear.
  4. Collect the blood. Touch the drop or drops of blood to the coffee filter and let it soak in. Use a fresh piece of filter for each chicken.
  5. Stop the bleeding. Dip the tip of the toe in styptic powder or plain corn starch. Bleeding usually stops quickly.
  6. Let it dry. Place the filter on a clean, dry surface and let it air dry completely, at least 10 to 15 minutes. Do not seal it while wet.
  7. Package the sample. Once the filter is completely dry, place it and the ID paper inside a small resealable bag.
  8. Label the bag. Write the same Bird ID and the date on the outside of the sealed bag with a permanent marker. The ID on the paper, on the bag, and on your registration must match.
  9. Clean between chickens. Clean and disinfect your clippers between each bird to prevent cross contamination. Wash or sanitize your hands as well.

Mailing your samples

  1. Put all the bags for one order into a single envelope.
  2. Write Batch followed by your batch number on the outside of the envelope. Your batch number is shown after you pay and is in your confirmation email.
  3. Mail it to:
    Hobby Hen Farms
    1550 Valley Home Rd.
    Morristown, TN 37813

    A regular stamped envelope is fine.
  4. Dried samples keep about a month at room temperature, so there is no rush, but please mail within two weeks of registering.

Important tips

  • Use clean clippers and sanitize between each chicken.
  • Keep everything clean and dry: hands, clippers, work area.
  • Only a couple of drops of blood are needed. One blood spot covers every test you ordered for that bird, sexing and gene tests alike.
  • Make sure the paper inside and the outside of the bag carry the same Bird ID.
  • Keep samples separated, sealed and dry, away from moisture, heat and direct sunlight.
  • Do not send wet samples, feathers, eggshell or anything other than the dried blood spot.

Only properly trained individuals should collect blood for testing. Consult with a veterinarian if you are unsure.
