Ok, so about a month ago we inherited a flock of 12 chickens - 10 hens, 2 roos. The roosters seemed to be fine together. One was definitely the alpha rooster but he tolerated the other rooster being around and didn't seem to mind him. I came home one day and found the alpha rooster pretty beat up - some gashes, feathers gone, etc. I figured one of our little dogs did it and not the other roo because the other rooster looked fine. Well ever since, the alpha rooster chases the other one away any time he tries to come around the flock, into the coop, etc. When they are all out free ranging the ousted rooster will go in the coop and eat and drink. At night, he sleeps in a little dog house (not used for dogs) that sits inside the run instead of in the coop with the alpha and the others. We thought maybe the alpha roo was mad because the other one didn't "help" him during the fight. Just wondering if anyone else has experienced this and if the alpha will ever let him become part of the flock again? Any suggestions on what we can do or should we just let them work it out?
