I have 6, 12 week old roos, 2 or 3 of which I want to keep for breeding. I already have a RIR Rooster. I will probably have all the roos in seperate pens and only use them for breeding. My question is, Will the Roosters go mean or aggressive, if they are always kept in pens? My RIR is in with 24 hens and he's ripping thier back feathers to shreds, I want to try and prevent this in the future and only have them breeding when I want them to. I have 40 hens total. What do you think?
