The one time I had a 50:50 ratio, as soon as the cockerels reached sexual maturity (before the pullets), those poor pullets had no peace. The boys were constantly chasing, gang breeding, and harassing them. They couldn’t eat, drink or dust bathe in peace without first one cockerel trying to mate, and another one or two more after that. And these birds were free ranged, so they had plenty of space. It only took a day or so before I got those boys all in a bachelor/ grow out pen so the girls could have some peace.
in your situation, I would build a bachelor pen or remove two or all three cockerels from your flock.
