- Order - a good rooster is the flock leader. Squabbling between hens seems to be much less with a rooster in charge.
- Locating the flock - in our pasture we're restoring, having a crowing rooster helps both me and adventurous hens locate the flock when it's not obvious
- Fertility - you can hatch your own chicks. This is really easy with a broody mama hen.
- I like roosters - they strut, they crow, they tackle hens in torrid spats of (brief) passion
Thier business is the ladies and business is good!
