I have been told that even with a small flock (I am raising for the eggs) that you should have one rooster for ever dozen or so hens, just to keep the hens in line. I have four pullets that just started laying and will soon have eight more. Do I need to have roosters or not? I do like the sound of them crowing. If so, what breed of rooster should I get? I will have six different breeds of hens to see which ones I like best.
