Just curious if anyone else has had or knew someone else who has had a bi-sexual chicken? I have a Hen+- that has laid a few fertilized eggs and sometimes tries to crow. Anybody? Should I call Ripely's?
I think we've gotten quite off track from our thread starter's stated reason for this thread. So I posted it again to try to answer their question. But first terminology needs to be clarified.
Many responders, as well as the OP, seem to be very uncertain about terminology as we discuss this issue of sexuality of animals, chickens in particular. So I'd like to clarify the terms that have been used, not all correctly.
Bi-sexual means being drawn to mate with either sex. Happens in most species.
Homosexual means being drawn to mate with the same sex, although in humans it also means sexual identity. Happens in most species.
Trans means nothing in animals because it involves gender dysphoria, an identity issue in humans which means being uncomfortable with the gender that was assigned at birth. The human person may have the organs and physical appearance of one sex while identifying as the opposite sex.
Androgynous, hermaphrodite, intersex all mean an individual has both female and male sex organs as well as secondary sexual characteristics of both sexes. In humans, they often identify as both male and female. In humans, they may be either a-sexual, not attracted to mate with either sex or bi-sexual, attracted to both sexes as sexual partners.
Those are the main ones. Whether people like it or not, sex cannot be nailed down neatly into just two categories. This goes for all living organisms, animal, human, insect, reptiles, that reproduce sexually. It's a continuum, irrespective of what your pastor or minister or state representative says.
But we are here to address the question the OP asked about their chicken. Let's break it down.
A hen that lays eggs that are fertilized is a chicken with a functioning ovary. That makes it a hen. If the eggs are fertilized, it's because the hen has mated with a rooster with functioning testicles.
If a hen crows, it only means that she likes to crow. Beyond that, it has nothing at all to do with her sexuality. She is simply a hen.
There are many variations, though rare, among chickens. Some variations are anomalies of anatomy at hatch and later maturity, others are the result of injury to sexual organs. These can result in Guinness or Ripply's type of animal "oddities" such as a hen with a damaged ovary triggering androgen hormones that cause her to develop male secondary characteristics such as rooster feathering and aggressive behavior. Or a rooster's testicle may be injured and testosterone is interrupted resulting in a "half and half" appearance developing. Then you have variations in individuals that refuse to mate at all or will be inclined to mate with either sex. It can get as confusing as human sexuality but without the psychological or transitioning expenses.
