WoS, I'm glad you've had the same thing, with the old alpha being dethroned easily like that. I thought it was really weird this last spring, my previous alpha got knocked down and I didn't even really notice! There didn't seem to be any fighting, nothing like that. One day Rocky was king, just as he had been for the last 4 years. The next day, Oops was king....it just seemed really out of the blue! I knew Rocky was getting up there, but it was so sudden and easy it kind of freaked me out. Like Rocky didn't fight at all, he just knew his time was over. Now, Rocky is beta and the two youngsters are under him, I though that was kind of weird, since Rocky had been de throned I though he would always be omega, but not so. Chicken society is sure fun to watch!
	
		
			
		
		
	
				
			
	
 I have a total of 21 birds right now, 6 of them (possibly 7?) are roosters. My coop is 6'x8', run about the same as yours, but anyone who doesn't feel like hanging out there simply flies out when they feel like it. I think - if they didn't have that option available - I might have a LOT more issues than I do at the moment! The biggest 4 compete for women with THE biggest playing "knight in shining armour" to those too young and not yet willing. I do have one that is not allowed to/afraid to eat breakfast with the others so I feed him seperately. Once in a while there will be a fight or a chase but, because they have the space, these don't get serious. At the same time, during afternoon siesta all the boys will be hanging out together in the same dust pit without complaint! Keep watching, you may find you'll either need to enlarge your run or build a second run (they'll be able to still share the coop, I'm sure!) or better yet, "chicken society" will sort itself out in a civilized manner and you won't have to do anything!
