Tony, I didn't mean to scare everyone away. My very limited opinion is--spend as much time as you can with them. Become part of the flock. Birds have personalities and quirks like people, dogs, etc... To say any "reeves pheasant" is going to be good or bad is a shot in the dark. What you can go on is: certain breeds are more apt to be aggressive. Silver, Reeves. Fireback, Elliot's, etc... are more likely to be aggressive to females or people than goldens or amhearst. Look at the different breeds of dogs. Which is more aggressive a golden retriever or a pit bull? Depends on the dog. Ok most likely pit bull. Point made. I have had pit bulls lick me in the face (Of course I was protecting my throat with my hand). Another point made, they are still wild animals, be cautious and prepared.
The reeves in the upper right is the dominant pheasant in that community pen. He is in charge. He knows I am no threat to him or his flock. Great bird. The reeves on the bottom left is his offspring. I kept them together hoping personality would rub off. Will remove well before breeding season.
Good luck.
