I've been slowly changing my flock over to Australorps over the past 4 or 5 years. Now that I have only Australorps, I'm wondering if my 5 year old roo needs to be replaced with a nice looking, 20 week old offspring of his. I'm raising for eggs (mostly); meat when there is an exessive amount of chicks in Spring & Fall. Normally, with the egg layer variety that I used to raise, I'd leave several roos out and let them decide who was alpha. It was never a problem keeping several roos in the flock of 20+ hens. But with the Australorps, my experience has been different. They will not tolerate any other roo and will fight to the death. Is this normal for this breed? I don't know. But I'm also wondering when I should replace the older roo since I can't leave several roos out and let nature take its course. Also, my foreigner, next door neighbors LOVE chicken fighting. I do not want to be a source of encouragement or entertainment for them. Therefore, I'm reluctant to throw my best roos together to let them work things out. Butcher dates are on the horizon and I must make a decision soon. Opinions anybody?
