If you haven't spoken to your neighbors, then you may be stressing for nothing.
She is 100% without a doubt, a female. If you are having this much anxiety over what others may think, it may be best to just re-home her.
Do not apologize for your anxiety. I understand.
How about we try looking at it this way...
Can you pinpoint exactly what is giving you anxiety? I know it's because of the crowing. What about it though? Let's try and work through it.
Honestly, just give her time. Nothing else you can really do.
Some people bring them in at night and put them out in the morning after crowing stops. I personally wouldn't worry about it. It will stop in time. If you get a complaint, then kindly explain what's happening and ask for forgiveness...
I'm sorry about your anxiety. She is definitely a pullet. Maybe you could have a talk with them and apologize for her crazy hormones? Explain that it should stop soon. Offer eggs when they start laying maybe?
Deep breaths. :hugs
As long as you haven't gotten any complaints, I say wait a bit. The crowing will stop and she will start laying.
Post some more photos in good lighting tomorrow. Ones that show her back and from the side.
She has a female specific pattern and no male specific feathers. Those two things do not lie.
She's right at the age where if she were male, those specific feathers and coloring would be coming in.
Are you not allowed roosters, or do just not want a crower?
