We had two young ones, male and female wander onto our property many years ago in a different house.
Months later, we found the owners and they wanted them back if we could catch them. We were ready to give them back. They had HUGH poops and their favorite place to be was on our patio and the rail of our porch. They came by in the mornings and late afternoons to watch "people TV" through our sliding glass doors of windows. If we were in the living room, they hunkered down and watched us. If we moved to the kitchen or living room they moved to the rail of the patio to watch through the windows. Fresh peacock poop squishes between your barefoot toes!!!!!
So my DH began to feed them on the ground, waited until they were both close together and then netted them. We placed them in dog crates and returned them to the owners who promptly placed them in a covered run to get them used to staying on their property. Apparently, the first time they had not kept them "in" long enough.
Good luck with yours!
