Where we live there are several "runaway" peafowl here in the desert so I never would've guessed they were all that delicate. Half the people love them, half absolutely hate them. Not much of a middle ground.
I personally have no experience with them, but I do enjoy hearing the ones from our neighbors 2 houses down. I think they sound neat but I'm weird like that.

I have noticed in several photos I've seen of enclosures for them, a lot fence in huge carports for them.
I've been down this road, hubby wanted some until we realized their requirements were more than we wanted to get into, and they would serve no purpose really other than as you said "ornamental".
