So out of my 8 straight run silkies, it turns out that 6 are roosters!! What are the odds?! Apparently 3:1, lol. I have 10 various other hens. All chickens are six months old but two of the roos are becoming quite aggressive and actually came after me today. Given the high number of roos and their aggressiveness I am going to rehome some. My question is how many roosters is a good number for the 12 hens? I've heard that you don't want just one rooster, but how many is a good ratio? Thanks!
