I have 3 peacocks (2 are 1.5 years old and one is 3) and 4 peahens. They are in an avairy that is 35 by 60. They have all been together for over a year with no problems. Today I came home and found 2 males in their 15x15 roosting area fighting. The white 3 year old has 2 small blood spots on his shoulder. Why are they now fighting and what should I do?
