OK, I know that roosters fight. Here is my delima, I have a ginormous fenced in chicken yard and all the birds get along great. I have an awesome bantam cochin roo that is so friendly and gets along with all the other roos and hens. I added 2 weeks ago a trio of modern games, with the roo being an old man. Everyone was getting along fine till yesterday when I looked out and saw a tumbleweed of feathers and beaks rolling across the pen! I ran out and they each had a beak full of the other and I had to open each ones beak to make them let go. I watched them for a while and after stepping in between them several times, they moved to opposite ends of the yard as if everything was fine. I thought it was the game roo that was the trouble maker, but this morning, when I let everyone out of the coop, the cochin made a bee-line after the MG and would not let up. So I gave him a time out in a cage for the day. I really would like to keep both of theys boys and let them have the freedom to roam in the large pen area, but does anyone have any tips on how to break the cochins want for going after the MG? He was not aggressive till yesterday and it is only towards this one roo. I DO realize that I may either have to give up one, or make another pen and seperate them, but thought that someone may have a suggestion where it is only a new behavior for this roo.
