peafowl staying home
They'll stick around I'm sure. If they are free range I would advise not clipping their wings. Clipping their wings has a couple down falls. First peafowl's main defense is flight. They use it to fly up high to roost to keep away from predators. Second peafowl with clipped wings and little children that don't know better tend not to go so well.
Are you planning to free range your peas? Peas are very curious and will roam very far if something interests them. If you are near any busy roads or have any unfriendly neighbors, this may be bad for the peas. Judging from my own experiences only, I don't think you can count on them staying near your house, or on being able to get them to come into a coop at night. They love to sleep high in the trees if at all possible!
