I have had my production red (the one in my avatar) in the same coop as my rosecomb phoenix for about a year and a half, and just las week the phoenix (dominant [only because hes older, and never actually had to fight the production red]) started chasing, and spurring the production red NON STOP. They always used to live in harmony, and leave eachother alone (until spring) and they have enough hens for both of them...... Whats goin' on?
