My six peafowl are now a year and a half old. They were raised from day olds with the chickens. They began freeranging at 8 weeks old and have been doing so ever since. For the first year they returned to the coop each night and slept with their chicken and duck friends. For the past several months they have been sleeping in the highest branches of the tallest tree over the chicken coop. A couple of weeks ago the temps were between 10-30 degrees all week and the peafowl did fine. On the night it snowed really hard for a long time, they did fly down and go in the stables. None of our chicken, geese, ducks, guineas or peafowl are caged or penned in any way and all are extremely healthy because they get to roam the yard and the woods and eat all the natural foods they desire and need. I love my peafowl - three males, three females, each a different color.
