Cattle Herding System (via shepherd staff)

An organic way to enable herding facilities into farming. (Putting this under the Mobs and Animals topic as the main goal is for behavior modification.)

Introducing the shepherd's staff: Crafted with 3 sticks. Goal is for optimized management of cows and sheep. 

Initiating mechanism: any cow/sheep that wheat is fed to once will become a part of your flock. (does not affect vanilla wheat breeding mechanic) 

Once staff is equipped, interact in the direction you would like flock to go, all closely surrounding animals that wheat was fed will head in that direction- only 5- 10 blocks at a time. Interact staff with a single animal and then send to direction, to isolate only one animal to move.

Extra uses:

• while migrating a herd, if staff is equipped - lowers chances of predators (wolves, ocelots, foxes) attacking.
• animals part of a flock will scatter and attempt to escape if being attacked by predators, but slowly rejoin the herd once threat is over, or guided back with the staff. 
• enchantments to the staff can extend to chicken, pigs, horses, donkeys. Efficiency to speed up animals, speed up rejoining the herd, and chances of getting stuck less. Retaliation enchantment to increase chances of herd attacking predators back.

This could definitely evolve gameplay for base game farming enthusiasts.
