Hi Sam, they look a little like Leghorn Bantams, but I can't be sure from the photo's.
Here are the Peafowl I'm looking at (so totally buying, no matter the cost of shipment). They appear to be 3 hens and a boy...
Their mother is photobombing them...
Actually, it's a nice story. The owner though they had lost her to a fox (and her eggs) only to have her show up a month later with this lot. Hen raised chicks are likely to raise their own, though I know someone who's Peahen was raised by a Chicken hen, and now it thinks she is a chicken and won't hang out with her Peacock...
I hope you get on well with your neighbours. lol
The males make a hell of noise in breeding season.
