I have three 7 month old Barred Plymouth Rock roosters and I have thirteen 16 week old pullets (RIRs, BOs, BSLs, EEs and 2 silkies). I have not mixed the roos with the pullets yet but I need to soon so the pullets will have access to their nest boxes. I've decided to get rid of two of the roos since that many roos on half grown pullets would be dangerous. My dilemma is I can't decide which roo to keep. Here is a description of each roo: Biggie Smalls: Largest, calmest, friendliest and possibly the most dominant though he had a cut on the back of his head from fighting one day. Kidd Rock: Medium sized, not extremely friendly but not aggressive or wild either. He seems to squawk and fluff up at the others alot. Frank: Smallest, not aggressive but not friendly, kind of flighty. I think he is the most submissive because he always comes out of the coop last and stays away from the other two a good bit. I don't know how each roo will behave with the girls but I'm wondering if it would be better to keep a smaller one since the pullets are kind of small now.
