Hypothetically-- Could you make a super friendly chicken breed?

[Amelise]

I'm daydreaming about the point when i'll have my own place and, therefore, as many chickens as I want. And while i'm at it, i'm thinking about different breeding projects that would be fun to work on (because I think it would be super fun to start a project and see my progress over the years.)
Anyways, i'm wondering if could I create a super friendly chicken breed? (i'm aware there already are friendly chicken breeds, but i'm thinking about friendly chickens that produce consistently friendly offspring. Also, i'm not just thinking about chickens that are simply docile enough to manage, but chickens that are personable and would love to be around people.)
By choosing the only snuggliest and least skittish of personalities, would one be able to eventually create a consistently friendly chicken? (with even consistently friendly roosters?) Would I have to worry about killing their survival instincts? Or could I get them to be friendly with humans but wary of predators?
If I was to go about it, would it be best to not socialize them as much as chicks, and wait to see which ones are naturally friendly, without any training, or would I try to make them as friendly as possible and just choose the friendliest ones?
I don't know, just something fun to think about

Generally yes it may be possible, but most of the time friendliness isn't passed on through reproduction/genes it is up to the bird itself.

Friendliness is up to the individual bird. Not really a trait.

I'm curious about how people were able to breed hyper aggressive roosters for fighting? Or is aggressiveness a trait but friendliness isn't?

My speckled sussex is my friendliest breed I used it in my project and all offspring since have been friendly.

So a temperament breeding project may be possible, but difficult?

Aggressiveness is a trait but most game birds/fighting cocks are actually pretty mellow unless they're trained.

The birds used for fighting weren't human aggressive though, how they view humans vs other birds is different

Some strains of Show Quality Silkie are bred too friendly that they're not that smart.

There's no training, that's false information. They're bred that way.
But that's also some conversation that's not really allowed on this site.
