Well I learned a little more about chicken/rooster behaviors today.
For the past week, our blk/lav split (father, named Mr Dummy) & our lav (his son, named Moose) have been fighting. The dad had always been flock leader for over 2.5 years but his larger son wanted to take over. Strange how they were fine for 8+ months previously. Needless to say Dummy did not want to give up his prominent role, so the poor guy kept getting his butt kicked by his more athletic son. We truly love and want to keep both. After the 1st big fight, we had to bring the father inside for observation & TLC. His comb was bloodied & he looked awful. Moose also had some scrapes but looked OK. During the day we put the old roo inside a chicken tractor to prevent fighting. The two roos would flare hackles at each other through the wire. Yesterday (after the initial wounds had healed) I finally let them figure it out. At one point, I saw Moose land on top of Dummy like a football tackle & Dummy stayed still. The dad seemed a little in shock & made what my kid called "hen noises." I had never heard him make such a noise & was very concerned. We brought him inside for the night & returned him to the chicken tractor this morning. As soon as we let the chickens out, Moose, (the victor) ran up to the chicken tractor with hackles flared. Mr Dummy did not flare his hackles & started making the strange hen noises again. From what I can tell, it's his way of admitting defeat. When I opened up the tractor, Moose chased, & Dummy ran away. I am sorry to see Dummy lose his position. He was a gentle, fair peacekeeper. Young Moose is still a big bag of hormones, so when given the choice, the hens prefer to follow Dummy. Although I can't say that I'm happy about the change in command, I can say that I'm glad they have finally stopped trying to kill each other. My hope is that in time, they will go back to working together as a team.
