Why is he doing this?

[ninjascrub69]

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?

Roosters housed together sometimes fight even if there are plenty of hens for both. It does seem a funny time of year -- too early for the spring hormonal surge, but on the other hand, winter (if you're in a cold-winter climate) is a time of boredom, which is a set up for behavior problems. I'd separate them before there is blood shed.

They are roosters being roosters. The Red may have decided to challenge the Phoenix and really ticked him off. Given enough space this may pass, but there is always the possibility that the Phoenix won't quit until he has eliminated the challenger.
