Big Girl is a lavender Orpington. First of all, "she" has extremely shredded feathers due to lavender color genetics. But that's the least of her issues.

Big Girl was one of a dozen straight run chicks purchased March 2018. Within a few months, it became obvious that five were males. That left 7 pullets including Big Girl. Two of the cockerels grew to a massive size, even larger than Big Girl. The other cockerels were comparable to her in size. But as they became teenagers, the cockerels began to crow, try to mount the pullets, & exhibit other typical cockerel behaviors. Big Girl's behaviors remained that of a sweet demure female, and so despite her unusual appearance, I never questioned her gender.

By the time the group reached 7-8 months of age, Big Girl was clearly different from all the rest. She was nearly twice the size of the other pullets, and her comb and wattles were larger too. Her feathering wasn't obviously male, but not fully female either. (The extreme shredded feathers made it even harder to tell.) She also grew spurs. But still she never exhibited any male behaviors whatsoever, continuing to act like a gentle and friendly girl. And so when she was 8 months old, I gave Big Girl her name.

The first two photos shows her general unique appearance.

Big Girl's shanks don't seem overly thick for a typical hen, but she has awesome spurs.

Here is a frontal view showing the size difference between her and a sister lav orp hen.

As far as behaviors, Big Girl has never laid an egg. She has never tried to mount a hen, nor has a rooster ever tried to mate with her. She doesn't get into fights with either sex. She has never tid-bitted a hen, but she hangs back and watches when i offer the flock treats. She doesn't watch the sky for predators, but doesn't usually forage with the hens either. Big Girl is very friendly and calm, but is mostly a loner.

Her appearance didn't change in later years due to an ovary that ceased to produce estrogen; Big Girl has always been this way. Whatever caused her to be so unique, I adore my gentle-natured, androgynous Big Girl.

Beautiful bird! :love :love I do know of a story of someone having a duck that was both, so who knows?

One thing: Age. You're saying it's 7-8 months old? Orpingtons can be slow to mature, so it can still be male. Is there other roosters around still? That can cause a rooster to be quiet and not prove themselves.

No eggs? Could still be slow maturing. Non dominant rooster. Some feathers look very hen like, but that doesn't mean it's a hen.

Also, hormonal imbalance. That could give the henny behavior and appearance, but can still be a rooster.

Give the bird some more time, and time should tell. Something that would give you 100% proof, but you probably wouldn't want to do, is cull. Cull, and study its parts. Just like the person with the duck. She couldn't figure out what she had, but that's how she figured it out.
 
Hi thank you for you reply. Big Girl was hatched March 2018, so she will be 4 years old this coming March 2022. When I mentioned "7-8 months old" , that was when I gave her her name. She has looked and acted the same Since she was 7-8 months old, back in 2018.

I would never cull her just to examine her sex organs ( she is an extremely sweet and gentle bird and has never caused a problem in any way.) But it has crossed my mind to perform/have performed a necropsy on her after she passes away. (Hopefully after she lives a long, good life.) I refer to Big Girl as "her" because her behaviors are female, but her appearance is not. I suspect she may be a true hermaphrodite. It may also be possible to have her DNA tested while she is alive; I'm not sure. Big girl is for sure an interesting chicken; I don't expect to ever have another like her!
 
Biology is weird! She’s probably a mixture of both. Maybe a bit of a sex chromosome got snipped off very early in development (this can happen with humans!) or genes for hormones got turned on/off when they shouldn’t have been. Lots of things can go screwy with sex development in all living creatures. It’s a super interesting subject imo. Glad she has such a loving home despite not laying eggs. 💕
 
Ever consider doing a DNA test just to see what it'd say? I saw one for about $14.
I didn't know where/how to get her DNA tested. And other than the fact that Big Girl is a curiosity, it's never been important for me to know. I'm hoping/assuming the DNA test will show if she is Both genders? The site you linked sounds cheap and easy. Im gonna follow up to make sure the lab has good reviews, & if so I'm gonna do it!
 
Google DNA sexing for parrots. It's super common and there are several places that can do it. Just check them for accuracy. Any avian vet can also do it, of course, it will be pricier. Doing it at home usually involves clipping a toenail a little short and collecting a blood sample, soaking a test card and mailing it off. However, I would find out if you can let them know that you suspect the bird may not be one single gender. Just so they don't through the test out as contaminated.

I just love this. I've cared for three like this now. None laid eggs, The roosters didn't bother them and they were accepted in their tribes just as they were.
I'll try and post a few pictures later.
