I don't know, I don't think it matters...they will establish a "pecking order" so to speak and it'll all work out. I'd get at least 2 more. Plus, this sounds mean, but it works. If you can get a hold of your rooster and hold him by his legs (he'll be upside down, hanging) let him hang that way for several minutes. Some really hate it and you have to coerce them into the hanging position...some go limp and quiet...but when you turn them right side up, they'll be calmer. I saw my grandma always do this and my dad done it. It works!! My dad had a MEAN turkey that always attacked him. He took him, flipped him upside down and held him by his legs for about 30 min. I don't see how on earth it could hurt them! That turkey NEVER pecked my dad again. What you are doing is showing the rooster or turkey or whatever, who is boss...and it's YOU! You are bigger and stronger. They realize that afterwards and calm down. I do it with my hens if they get feisty and they calm right down.
