Hello,we have 3 pheasants and they all turned out to be male:2 are red golden and 1 is lady amethyst. One of the red golden is couple of months older than the other 2. When they were little the ones that are the same age were doing pretty good together and the older one was chasing them. Now they both ganged on one of the little ones. And they pull his tail feathers out. Is there anything we can do to stop them? I really don't want to give him away.
