I know you are probably kidding about the 50 neurons, but Red Junglefowl (what chickens are derived from) are working with 221 million neurons. Which isn't that much in the grand scheme of things, but more than double the amount compared to a quail and about the same as a parrotlet or a brown rat.

Yes, they do have very clear personalities. We had one who was very curious about people, just very interested in following you and seeing what you do. It's probably food related motivation, but more than simply seeking a handout as most of them do. You could really see the gears turning in there.

Befriending one of the more intelligent birds (jays, or crows) is also very entertaining, though they are still wild of course.

>50 neurons they're working with in life.

so approximtely 10x more than me on mondays before caffeine

you dont need bazillions of neurons to showcase complex behavior. also in humans a large part of our brain is to help us move on 2 legs and keep us balanced.
