this spring i purchased 7 straight run bantams and 7 standard hens. well 5 of the 7 bantams are roosters . we already love them and all are very sweet with the exception of my black cochin...he is aggressive already. i think the ratio is 1 roo to 10 hens...is that correct? also, since the roosters are bantams and i do have 7 standard hens plus my two bantam hens does that change the ratio? i really do want to keep 4 of the roo's but not if that will disrupt my flock.
