I would go for a peahen around his age. You could get an older peahen but normally older peahens pick on young males so if you can I would try and find a peahen a year old or about a year old.
Also Peas can be very friendly but not in a touchy feely way, they like to be around you more if you don't try to touch them, look at it this way they don't go around touching each other and when they do they are to get out of the way of the one touching them.
Some of mine love their head scratched but i raised them from hatch so they are very imprinted on people , they will stand right next to you and you can reach down and just pick them up but they do not like it, don't never stop mine from standing there again though
