I have a flock of 4 hens, all 1.5 years old. Another flock (separate coop) of 10 are 5 months old, and we just figured out we have two roosters in there! They're getting along so far, but I know what's coming... I've integrated younger and older hens before (a painful experience no matter how you go about it, in my opinion!), but never a roo. My question is: Will a nice, big 5-month-old Buff Orp roo be able to hold his own with 4 mature, set-in-their-ways ladies? We figure we'll put the bigger, more mature, more feisty roo in with them, and let the smaller, quieter one stay with the girls he knows. Do roos tend to handle this better than pullets because of their hormones, or is that just wishful thinking? Thanks for any advice you can give me!
