DNA sex testing
1 to 28 tests in an order: $8 per test.
29 or more tests in the same order: $7 per test.
The discount applies to every sexing test in the order, not just the ones over 28. Gene tests are priced per bird as shown below and do not count toward the 29-test tier.
Examples
- 3 birds: $24
- 10 birds: $80
- 28 birds: $224
- 29 birds: $203
- 30 birds: $210
- 50 birds: $350
- 10 birds sexed, blue egg gene on 3 of them: $80 + $36 = $116
- 1 bird, sexing plus all four gene tests: $8 + $14 + $14 + $12 + $12 = $60
How payment works
- You pay by card at the end of the registration form, through Stripe. Hobby Hen Farms never sees or stores your card number.

- The total is shown on the form before you pay and again in your confirmation email.
- Postage to mail your samples is not included.
What is included
- Every test you tick for each bird: DNA sexing and any gene tests
- Each result beside its Bird ID in your private account
- An email the moment your results are released, usually within 24 hours of your samples arriving
Gene tests
Add any of these to a bird when you register it. Tick the tests you want on each bird’s line; the same blood spot covers all of them. You can order a gene test with or without sexing.
- Lavender gene: $14 per bird (carrier or non-carrier)
- Recessive white gene: $14 per bird (0, 1 or 2 copies)
- Frizzle gene: $12 per bird (0, 1 or 2 copies)
- Blue egg gene: $12 per bird (0, 1 or 2 copies)
Lavender Gene Test — $14 per bird
Find out whether a bird carries the lavender (self-blue) gene before you breed it. Lavender is recessive, so a normally colored bird can carry it and pass it on without showing it. This test tells you which of your birds are split to lavender.
Results you’ll receive:
- Lavender carrier: at least one copy of the lavender gene detected. For a normally colored bird, this means it is split to lavender.
- Non-carrier: no lavender gene detected.
Please read before ordering:
- This test does not separate one-copy carriers from two-copy (visibly lavender) birds. Visibly lavender birds are already two-copy, so there is no reason to test them. Test the birds that don’t look lavender.
- It detects only the lavender gene. It won’t tell you about blue, splash, chocolate, or other dilutions that can look similar.
- Sample: a drop of blood on coffee filter paper, same as our sexing test. One sample covers sexing and every gene test we offer if ordered together.
- If a sample fails, we rerun it from the remaining blood at no charge; repeated reruns for collection errors aren’t guaranteed.
Recessive White Gene Test — $14 per bird
Recessive white hides whatever color pattern a bird is carrying underneath, and a colored bird can carry one copy without showing it. This test tells you how many copies of the recessive white gene a bird has, so you can pair birds on purpose instead of guessing.
Results you’ll receive:
- C/C – not recessive white: no copies of the gene.
- C/c – carrier: one copy. Looks colored, can produce white chicks when paired with another carrier or a white bird.
- c/c – recessive white: two copies. The bird is white because of this gene.
Please read before ordering:
- This test looks for the recessive white gene only. Dominant white (the gene behind White Leghorns and many commercial whites), silver, and other reasons a bird can look white or pale are not tested, so a white bird can come back C/C.
- Chickens only.
- Sample: a drop of blood on coffee filter paper, same as our sexing test. One sample covers sexing and every gene test we offer if ordered together.
- If a sample fails, we rerun it from the remaining blood at no charge; repeated reruns for collection errors aren’t guaranteed.
Frizzle Gene Test — $12 per bird
Frizzle is a dominant gene with a catch: one copy gives the curled feathers people want, two copies gives a “frazzle” with brittle, sparse feathers and health problems. This test tells you exactly how many copies a bird has, so you can plan pairings with confidence.
Results you’ll receive:
- f/f – no frizzle gene: smooth feathered, will not throw frizzles.
- F/f – one copy: a normal frizzle. Pair with a smooth (f/f) bird for about half frizzle chicks and no frazzles.
- F/F – two copies: a frazzle. Pairing this bird with anything produces only frizzle-carrying chicks, and frizzle × frizzle pairings are how frazzles happen.
Why test:
- A smooth-looking bird from frizzle lines can occasionally still carry the gene when other genes soften the curl. This test confirms it.
- A heavily curled bird can be F/f or F/F, and the two can be hard to tell apart on young birds.
Please read before ordering:
- This test detects the common frizzle mutation (KRT75). It does not detect the separate mutation found in Kirin chickens, which are rare in the US.
- Chickens only.
- Sample: a drop of blood on coffee filter paper, same as our sexing test. One sample covers sexing and every gene test we offer if ordered together.
- If a sample fails, we rerun it from the remaining blood at no charge; repeated reruns for collection errors aren’t guaranteed.
Blue Egg Gene Test — $12 per bird
The blue egg gene is dominant, so a hen with one copy lays blue or green eggs just like a hen with two copies. The difference shows up in her chicks: a two-copy bird passes the gene to every chick, a one-copy bird passes it to about half. Roosters carry and pass the gene too but never lay an egg to show you. This test tells you exactly how many copies a bird has.
Results you’ll receive:
- o/o – no copies: will not produce blue or green egg layers on its own.
- O/o – one copy: lays blue or green eggs; about half of its chicks get the gene.
- O/O – two copies: lays blue or green eggs; every chick gets the gene.
Why test:
- Pick breeding roosters and cockerels that will pass blue to every chick.
- Confirm an Ameraucana, Araucana, Legbar, Easter Egger or Olive Egger breeder is O/O before selling chicks as guaranteed colored-egg layers.
- Sort pullets long before their first egg.
Please read before ordering:
- This test tells you about the blue egg gene only. It does not predict the shade. Green and olive eggs are blue eggs with a brown coating from separate genes, and brown-coat genetics are not tested.
- Chickens only.
- Sample: a drop of blood on coffee filter paper, same as our sexing test. One sample covers sexing and every gene test we offer if ordered together.
- If a sample fails, we rerun it from the remaining blood at no charge; repeated reruns for collection errors aren’t guaranteed.
