You can pen or free-range peafowl. If you want to free-range them it is best to start with yearlings. Keep them penned for a month or more, then let them out one at a time and for short amounts of time until finally you have them fully free-ranging. Also you can just keep them penned or do both have some free-ranging and some penned. We mainly feed our peafowl sunflower seeds and a mix of corn, wheat, and some other stuff in a mix called 5 way the feed store mixes for us and other bird people. I think most feed theirs laying mash or something...I am not the food expert we don't really feed ours all the stuff everyone else does, but they will eat leftovers too like old lettuce, old bread, grapes, tomatoes, apple slices, sometimes banana, all sorts of stuff can be good treats. I like training them to eat out of my hand by using peanuts. That is their favorite treat and now I have all of my peafowl eating peanuts out of my hands. If you pen them they will need roosts as high as possible because they love high roosts. If they are free-range they will roost very high up in the trees.
