If your wanting to keep her around then just keep doing what you are now. Put out feed and water for her. She can fly and get away from dogs, cats are her worse predator, attacking her while on her roost at night.We don’t have enough room. We only have two pens. One for ducks and one for chickens. She’s not ours nor do we know where she came from. We are happy to keep her, but it’d made our life easier if we could keep her with our other animals as we have dogs that run down there. We’re already attached and don’t want to get rid of her but if it’s what’s best then we will.
Tony is absolutely correct, you don't want chickens, ducks, geese, guineas, etc...around pheasants because of the reasons he stated.
She may stay around or she may move on, it's a toss up as to what may happen.
