I have a 6 mo old turkey that came from the animal shelter in with my flock of 8 chickens and 1 crested duck. This is not a question about whether or not they should be together (I'm not worried about blackhead currently, and everyone is tested and free of diseases/keep up on parasites) but if turkeys are aggressive. My crested duck's head was plucked bald and is bloody, and I'm guessing it was the turkey, but am not sure. He's been here for over a month, but this just started. Any advice from people who know turkey behavior? He has not bothered the chickens other than chasing them around.
