I eat them, add them to my free range bachelor coop (in which case they may still get eaten) or sell them off with excess pullets in pairs and trios. Occasionally I have someone looking for just a cockerel, but not often. Pullets here aren't sold without a cockerel unless I manage to get rid of all the boys and still have extra girls left over (doesn't happen very often).
I do the same add them to my free range flock. Let them grow out then put them in the freezer. They get to live a good life on 8 acres till there culled. And sometimes I keep one if it has a special personality I just can't help it.
