Indian Blue;
We have on Peacock we raised from a young bird. It has adapte well with our chickens and ducks. When he was a little over half grown he didn't want to go in with the chickens. We had to coax him in each night. I can whistle now and he knows he is somewhere he is not supposed to be.
I worry sometimes when I catch him going toward the road. He is curious to a fault. Once while I was working in the barn I saw the neighbors dog creeping toward the barn on his stomach. I went to the door and found the peacock creeping toward the dog.

I chased the dog off and those neighbors have since moved. Our chickens for the most part stay inside the fence. The peacock can fly over the barn.
I'm not sure we need more than one peacock. Some friends a few miles away have a larger farm and some woods. They have several peacocks and sell the feathers.
