Meet Angevine, I found her at the river

I don’t think there’s a need for that. No male specific feathers at all. No saddles or sickles. And it’s not a young bird.
It’s a female.

A hen - perhaps with the start of an ovarian/hormonal imbalance. Mature/old - no SLM.

Agreed. That's a hen.

If you three say so, then a hen she is!

^ Oh, and you ^

Old girl. Probably wither bolted in a predator attack or got dumped if her laying slowed

 

[I Love Feather Babies]

A cockerel, who has had his testes removed so he becomes nice and fat like a hen. It is done so he is table ready

 

[MeanCheek]

In Spain, they caponize a lot of there cockerels. Then they force feed them

 

[Tookie]

Ok, I was totally wrong.

 

[All4Eggz]

Agreed, a hen with what seems to be a hormonal imbalance.
She does not appear to have SLM.

 It crows every morning (only in the morning, though), hasn't layed any eggs, tidbits, hasn't bred a hen but hasn't been bred by a roo?

We see this fairly often in here. What you have is a hen who at some point had her functioning ovary damaged (chickens only ever have one functioning ovary.) When this happens the hen will take on characteristics and behaviors of roosters. They cannot lay because the ovary is no longer functional. They generally grow abnormally large combs but usually not male specific feathering. They may even mount other hens but they are infertile. So what to do with her is the question. She probably won't cause any harm in your flock but you may not want a chicken that crows yet cannot lay or fertilize eggs.
